php-lsp

Rust PHP Language Server (LSP 3.17) with a VS Code extension.

php-lsp targets PHP 7.4-8.4 projects and provides indexed PHP language intelligence: diagnostics, hover, completion, navigation, references, rename, formatting integration, semantic tokens, hierarchy views, and built-in phpstorm-stubs support.

Features

Language Intelligence

• Syntax diagnostics with incremental tree-sitter parsing.
• Semantic diagnostics for unknown classes, functions, imports, members, and duplicate workspace symbols.
• Member diagnostics for visibility, static/instance misuse, missing methods, missing properties, and missing class constants.
• Basic type compatibility checks for assignments, returns, arguments, properties, and member calls.
• Best-effort PHPDoc template metadata, PHPStan/Psalm type aliases and imported aliases, and inherited generic member type substitution for common repository and collection patterns, including foreach values from PHPDoc-generic collection returns.
• Call-site inference for PHPStan/Psalm conditional return types and class-string<T> factory/service-locator patterns in hover, completion chains, local variable type inlay hints, and Doctrine getRepository<T>() / repository find* hovers.
• Shape-aware inference for PHPDoc array{...} / object{...} and literal array shapes in completion and key navigation.
• Closure and arrow-function parameter inference from callable(...) signatures, including generic map/filter-style collection callbacks and array_map-style helpers.
• Framework-aware static providers for common Laravel string keys, Symfony Twig template names, and Symfony route names without booting the application.
• Blade-like and Symfony/Twig template documents use virtual PHP plus source maps for conservative hover, completion, definition, inlay hints, diagnostics, and semantic tokens in supported template expressions and control blocks.
• Override signature and PHP-version compatibility diagnostics.
• Optional PHPStan and Psalm diagnostics through configured external commands.
• Per-category diagnostic severity controls for unknown symbols, unused code, duplicate symbols, members, type compatibility, override signatures, and PHP-version checks.
• Test-friendly diagnostics for common PHPUnit patterns, including assertion helpers, test doubles, trait-based test helpers, anonymous classes, and closure/destructuring variable scopes.
• Hover for symbols, source-like PHP signatures, linked FQN/source metadata, class and method-level relation links, template/generic bindings, Symfony/Doctrine framework roles, indexed PHP 8 attributes, complete parameter lists, types, variables, PHPDoc summaries/descriptions, deprecation, and PHPDoc virtual members, plus call-site-specialized generic return sections with clickable class links where the target can be resolved.
• Completion for classes, interfaces, traits, enums, functions, constants, methods, properties, variables, namespaces, keywords, snippets, PHPDoc virtual members, shape keys/properties, framework string keys, template paths, and auto-import edits; incomplete one-line $object-> expressions remain usable for completion while tree-sitter diagnostics still report the incomplete PHP.
• Completion resolve enriches PHPDoc virtual member completions.
• Signature help for functions, methods, constructors, and active parameter tracking.
• Inlay hints for argument labels, inferred PHPDoc parameter/return types, useful inferred local variable types, and end-of-scope labels for methods and large blocks.
• Semantic tokens with full, delta, and range requests.

Navigation

• Go to definition for indexed symbols, local variables, $this, constructors, PHPDoc virtual members, PHPDoc/literal shape keys, static framework string keys, template paths, Symfony Twig route keys, and lazy vendor fallback.
• Go to declaration for imports, with definition fallback.
• Go to type definition for inferred variables, members, function returns, and indexed symbol types.
• Go to implementation for interface/trait/base types and methods.
• Find references through indexed per-file references and same-scope local variable references.
• Document highlight for local variables and non-local symbols.
• Selection ranges based on the parsed AST.
• Linked editing for namespace/use alias edits.
• Document links for statically resolvable include/require paths.

Symbols And Hierarchies

• Nested document symbols for namespaces, types, and members, including signatures and deprecation tags.
• Ranked workspace symbol search over the indexed workspace.
• Call hierarchy for functions, methods, constructors, incoming calls, and outgoing calls.
• Type hierarchy for classes, interfaces, traits, enums, supertypes, and subtypes.

Refactoring And Editing

• Rename for classes, functions, methods, properties, constants, and local variables.
• Prepare rename rejects unsupported or built-in targets before editing.
• Quick fixes to import unresolved classes/functions, remove unused imports, apply diagnostic replacement metadata, and optionally map PHPStan/Psalm findings to local fixes.
• Source action to organize imports.
• Quick fix to implement missing interface, abstract parent, and abstract trait methods while preserving PHPDoc, analyzer tags, attributes, visibility, static, params, defaults, and native-safe return types.
• Refactor actions to generate constructors and property getters/setters from indexed properties.
• Refactor actions to change member visibility and promote simple constructor assignments to constructor property promotion.
• Refactor action to synchronize PHPDoc @param and @return tags from function/method signatures while preserving richer analyzer-specific tags.
• Refactor action to add return types from PHPDoc when supported by the target PHP version.
• Refactor actions to extract selected expressions to local variables, extract class-scope literals to constants, and inline simple same-block local variables.
• Heavy refactor edits use codeAction/resolve so initial code-action requests stay lightweight.
• Document formatting, range formatting, and on-type formatting through auto-detected or configured external formatters (pint, php-cs-fixer, phpcbf, or a custom command).

Editor UI

• Status bar popup with indexing status, file/percentage progress, symbol count, stubs information, active diagnostics/analyzers, formatter, include paths, and server binary details.
• Code lenses with reference counts.
• Folding ranges for PHP structures, comments, arrays, and blocks.
• Document formatting and range formatting through auto-detected or configured external tools.
• On-type indentation edits for newline, semicolon, and closing brace.

CLI And Tooling

• Running php-lsp without a subcommand starts the LSP server on stdio.
• php-lsp init-config creates a starter .php-lsp.toml file.
• php-lsp analyze [PATH] runs the same parser, workspace index, and built-in diagnostics pipeline from the command line.
• analyze supports --project-root <DIR>, --severity <all|hint|info|warning|error>, and --format <table|json|github>.
• Analyze output is available as a local table, stable JSON for scripts, or GitHub workflow annotations.
• php-lsp fix [PATH] --dry-run previews safe native fixes without writing files.
• fix supports repeated --rule values for unused-imports, organize-imports, and add-return-type, plus --format <table|json>.

Workspace Support

• Initialization options and runtime configuration updates through workspace/didChangeConfiguration.
• Composer autoload support for PSR-4, PSR-0, classmap, and files entries.
• Additional include and exclude paths from extension configuration.
• Built-in phpstorm-stubs bundle with configurable extension stubs.
• Lazy vendor/ indexing.
• Multi-root workspace support.
• Watched PHP file changes and LSP file-operation notifications.
• Create/change/delete PHP file events reindex or remove symbols from the workspace index.
• Rename file notifications move indexed file state from old URI to new URI.

Known Limitations

• Production validation was refreshed on 2026-05-28 after the IDE intelligence milestone. It measures a primary 10k-file Symfony workspace and two additional Laravel-like workspaces. Remaining GA work is tracked in docs/production-risk-register.md and docs/production-baseline.md.
• Workspace, stub, and lazy vendor file symbols are cached in separate disk namespaces with mtime, size, and content-hash validation. Lazy vendor files are persisted after the requested class is verified in the index; Composer vendor metadata is cached in memory with an LRU for lazy vendor symbols. The primary large-workspace warm cache target is met; installed-vendor first-hit behavior remains a watch item.
• references, rename, and reference-count code lenses use indexed per-file references, but still iterate workspace reference sets and can be expensive on very large repositories.
• Workspace indexing parses files through a bounded CPU-aware task queue; the primary large-workspace indexing baseline is measured in docs/production-baseline.md.
• Heavy references/rename requests, background indexing, and external analyzers have cancellation coverage; some other heavy requests remain benchmark watch items.
• Rapid didChange bursts still refresh parser/index state on each accepted edit, while diagnostics are debounced and version-checked.
• Built-in stubs are configurable and version-filtered for supported phpstorm-stubs version-gating metadata. New metadata forms may require parser updates.
• Cross-file local variable analysis is intentionally limited; variable references and rename are local-scope oriented.
• Type inference includes common PHPDoc generic inheritance bindings, class-string<T> call-site bindings, conditional return fallbacks, and Doctrine repository call-site bindings, class/file-scoped PHPStan/Psalm type aliases, callback parameter inference, Generator<TKey,TValue> foreach key/value inference, and best-effort PHPDoc/literal shapes, but it is still shallow compared with mature PHP static analyzers.
• Built-in semantic diagnostics depend on indexed project and vendor symbols. If Composer/vendor metadata is absent, external framework classes can be reported as unknown; dynamic framework APIs such as some Eloquent relation members are best-effort.
• Template support is conservative. Blade-like and Twig documents are not full template-engine implementations; diagnostics are best-effort and published only for a small allowlist of exact source-mapped expression errors plus conservative Twig delimiter/block syntax errors; generated virtual PHP, incomplete/magic properties, and uncertain ranges stay suppressed. Complex Twig expressions such as filters, tests, in, functions, macros, ternaries, null coalescing, and dynamic/bracket attribute access are explicit best-effort backlog items; their full expression semantics are skipped rather than mapped to misleading PHP, while simple member chains and root variables inside those expressions can still be source-mapped for hover/completion/definition. Type-preserving Twig filters such as slice and filter keep the base collection available for foreach hover/completion/definition/inlay inference. Twig object completion also offers getter-derived property-style labels such as id for getId(). Definition can still navigate static Twig template-path literals that exist under templates/, including HTML attribute values, and Symfony path() / url() route keys backed by PHP 8 #[Route(name: ...)] attributes. Twig foreach over Doctrine entity collections exposed through property-style access can infer item hover/completion/definition/inlay types from indexed ORM targetEntity property metadata and add*/remove* collection mutator signatures. Twig attribute access over PHPDoc and inferred array shapes can expose shape-key hover, completion, source-backed definition, and inlay types for patterns such as row.messageLog, nested config_params.sftp.port, and local {% set message_log = row.messageLog %} variables. Shape-key definitions point at the PHPDoc shape key or literal array key when the static context scanner has that source range. Twig context variables are inferred from static render(..., [...]) call sites and literal-template helpers whose next argument is a context array, including new Class(), arrays of new objects, typed controller parameter variables, nullable locals assigned conditionally before render, indexed $this->service->method() return types, iterable repository method results, literal nested array shapes, $items[] = [...] append-built shapes, common array_values / array_filter / array_map / explode / preg_split list pipelines, compact('name') variables, Doctrine magic find* / findOneBy* repository results, and Knp-style paginator variables backed by Doctrine repository/query-builder sources. One-level Twig {% include ... with {...} %} calls can pass those inferred caller variables into component templates, so included partials can resolve foreach item hover/completion/definition and inlay hints without hardcoded template names. Custom Doctrine repositories can be resolved from indexed @extends ServiceEntityRepository<Entity> PHPDoc or ORM repositoryClass attributes without synchronous request-time source reads; render keys whose value type cannot be inferred are still seeded as mixed to avoid false undefined-variable diagnostics. Open Twig documents refresh those inferred context types after relevant PHP controller/render changes and workspace reindex events.
• Diagnostics are optimized for editor feedback: file changes publish fast in-process diagnostics, while full diagnostics and optional external analyzer runs are used on open/save and reconfiguration.
• External PHPStan/Psalm diagnostics require those tools to be installed and configured by the workspace.
• Formatting is delegated to external tools; php-lsp auto-detects common Composer dev tools but does not implement or advertise a native PHP formatter provider.

Configuration

The VS Code extension contributes these settings under phpLsp.*:

Runtime environment:

Environment variable	Default	Description
PHP_LSP_WORKER_THREAD_STACK_SIZE	8388608	Tokio worker-thread stack size in bytes. Values below 1 MiB are ignored. Raising this can help unusually deep framework/type/template workloads, but the default is intended for normal editor use.

Setting	Default	Description
phpLsp.enable	true	Enable the language server.
phpLsp.phpVersion	8.2	Target PHP version for diagnostics and version-aware refactors (7.4-8.4).
phpLsp.serverPath	""	Custom server binary path. Empty uses the bundled binary, then falls back to php-lsp from PATH if the bundled binary is missing.
phpLsp.includePaths	[]	Additional relative or absolute directories/files to include in workspace indexing.
phpLsp.excludePaths	[]	Relative or absolute directories/files to exclude from workspace indexing.
phpLsp.stubs.extensions	All available stubs	PHP stub extension set to index from the bundled stubs. Leave unset to discover all extension directories; set [] to disable stubs.
phpLsp.composer.enabled	true	Enable composer.json autoload indexing.
phpLsp.indexVendor	true	Index vendor/ lazily.
phpLsp.diagnostics.mode	basic-semantic	off, syntax-only, or basic-semantic.
phpLsp.diagnostics.severity	Category warnings	Per-category severity for unknownSymbols, unused, duplicateSymbols, members, typeCompatibility, overrideSignatures, and phpVersion; values are off, error, warning, information, or hint.
phpLsp.diagnostics.memberTypeNodeBudget	512	Relevant AST-node budget for expensive member/type diagnostics per file. Set 0 to disable the cap.
phpLsp.diagnostics.partialAnalysisDiagnostic	true	Publish an informational diagnostic when member/type diagnostics are skipped by the budget.
phpLsp.allowProjectCommands	false	Trust executable analyzer and formatter settings from .php-lsp.toml. Keep disabled for untrusted workspaces.
phpLsp.formatting.provider	auto	auto, none, pint, php-cs-fixer, phpcbf, or custom.
phpLsp.formatting.command	""	Custom formatter command; use {file} for the temporary PHP file.
phpLsp.formatting.timeoutMs	30000	External formatter timeout per request.
phpLsp.phpstan.enabled	false	Enable PHPStan diagnostics.
phpLsp.phpstan.command	vendor/bin/phpstan ... {file}	PHPStan command that prints JSON output.
phpLsp.phpstan.timeoutMs	30000	PHPStan timeout per file.
phpLsp.psalm.enabled	false	Enable Psalm diagnostics.
phpLsp.psalm.command	vendor/bin/psalm ... {file}	Psalm command that prints JSON output.
phpLsp.psalm.timeoutMs	30000	Psalm timeout per file.
phpLsp.analyzerCodeActions.enabled	false	Enable opt-in quick fixes for PHPStan and Psalm diagnostics when diagnostic metadata is available.
phpLsp.trace.server	off	LSP transport trace: off, messages, or verbose.
phpLsp.logLevel	info	Server log level: error, warn, info, debug, or trace.

Shared project defaults can also be stored in .php-lsp.toml. Use php-lsp init-config to create a default file without overwriting an existing one. Config precedence is built-in defaults, global config, project config, then explicit VS Code settings. Executable analyzer and formatter settings from project config are ignored unless phpLsp.allowProjectCommands is enabled in VS Code or allowProjectCommands = true is set in global php-lsp config. See Configuration.

Example external diagnostics setup:

{
  "phpLsp.phpstan.enabled": true,
  "phpLsp.phpstan.command": "vendor/bin/phpstan analyse --error-format=json --no-progress --no-interaction {file}",
  "phpLsp.psalm.enabled": true,
  "phpLsp.psalm.command": "vendor/bin/psalm --output-format=json --no-progress {file}",
  "phpLsp.analyzerCodeActions.enabled": true
}

When the same analyzer settings are stored in project .php-lsp.toml, php-lsp requires explicit workspace-command trust before it executes them. Prefer VS Code user/workspace settings or global php-lsp config for commands in repositories you do not fully trust.

Example external formatting setup:

{
  "phpLsp.formatting.provider": "php-cs-fixer"
}

Formatter resolution order:

1. Explicit phpLsp.formatting.* settings, global php-lsp config, or trusted .php-lsp.toml [formatting] values.
2. Composer metadata auto-detection from require-dev/require: laravel/pint, friendsofphp/php-cs-fixer, then squizlabs/php_codesniffer.
3. No formatting provider when no explicit provider or supported Composer tool is available.

External formatter commands are timeout-bound and cancelled when the document changes, closes, or a newer formatting request supersedes the old one. Range formatting stays conservative: php-lsp formats only the selected fragment via a temporary file and never silently formats the whole document for a range request.

CLI

php-lsp analyze [PATH] --project-root <DIR> --severity warning --format table
php-lsp fix [PATH] --dry-run --project-root <DIR> --rule unused-imports --format json

PATH can be a PHP file or directory. When it is omitted, php-lsp analyzes the effective project root. CLI commands load the same global/project .php-lsp.toml configuration used by the language server for PHP version, diagnostic mode/severity, Composer discovery, and include/exclude paths.

Analyze exit codes:

Code	Meaning
0	No diagnostics at the requested severity.
1	Execution or configuration error.
2	Diagnostics were found.

Output formats:

Format	Use
table	Human-readable local output.
json	Stable machine-readable report with schemaVersion, summary, and diagnostics.
github	GitHub Actions workflow annotations.

Fix dry-run mode:

• php-lsp fix currently requires --dry-run and refuses to write files.
• Without --rule, it runs the preferred safe native fixers: unused imports and PHPDoc-derived return types that can be represented as native PHP return types for the configured PHP version.
• --rule can be repeated. Supported values are unused-imports, organize-imports, and add-return-type.
• Exit code 0 means no edits would be produced, 1 means execution or configuration error, and 2 means edits would be produced.
• The fix command does not run project formatters.
• CI and local example scripts are documented in CLI And CI Usage.

Commands

The extension contributes these VS Code commands:

Command palette title	Command ID	Behavior
PHP: Show Language Server Status	phpLsp.showStatus	Opens the status quick pick with indexing, cache, stubs, diagnostics, formatter, analyzer, and server-binary details.
PHP: Show Language Server Version	phpLsp.showServerVersion	Shows the initialized server name/version plus resolved binary, platform, stubs, cache roots, and last startup errors.
PHP: Restart Language Server	phpLsp.restartServer	Restarts the client/server process and reuses the existing disk cache.
PHP: Clear PHP LSP Cache and Restart	phpLsp.clearCacheAndRestart	Deletes cache directories for current workspace roots and discovered Composer roots, then restarts the server.

Troubleshooting

Server Does Not Start

• Check PHP: Show Language Server Status or PHP: Show Language Server Version for the resolved server binary path, source, platform target, and last startup error.
• If phpLsp.serverPath is set, verify that it points to an executable php-lsp binary.
• If using the bundled binary, verify that your platform is one of linux-x64, linux-arm64, darwin-x64, darwin-arm64, win32-x64, or win32-arm64.
• If the bundled binary is absent and phpLsp.serverPath is empty, the client tries php-lsp from PATH and logs the selected source in the LSP output channel.
• Set "phpLsp.logLevel": "debug" and "phpLsp.trace.server": "messages" for more output.

Indexing Is Slow Or Stale

• Use PHP: Show Language Server Status to inspect indexed file count, cache path, stubs path, include/exclude paths, and analyzer settings.
• Add generated directories to phpLsp.excludePaths.
• Keep phpLsp.indexVendor enabled for lazy vendor lookup, but exclude very large generated vendor subtrees if they are not useful.
• Use PHP: Clear PHP LSP Cache and Restart when changing branches, Composer metadata, stubs, or project layout and the disk cache looks stale.

Diagnostics Are Too Noisy

• Ensure Composer metadata and vendor/composer/installed.json are available when you want built-in diagnostics to resolve external framework symbols.
• Set "phpLsp.diagnostics.mode": "syntax-only" to keep only parser syntax diagnostics, plus conservative Twig syntax diagnostics for Twig documents.
• Set "phpLsp.diagnostics.mode": "off" to disable built-in diagnostics.
• If a large file reports partial analysis, raise "phpLsp.diagnostics.memberTypeNodeBudget" or set it to 0 to run member/type diagnostics without that cap.
• Prefer per-category severity controls when only one category is noisy:

{
  "phpLsp.diagnostics.severity": {
    "members": "off",
    "unused": "hint"
  }
}

PHPStan Or Psalm Diagnostics Do Not Appear

• Enable the analyzer explicitly with phpLsp.phpstan.enabled or phpLsp.psalm.enabled.
• If the analyzer is enabled only in .php-lsp.toml, also enable phpLsp.allowProjectCommands after you trust the workspace.
• Make sure the configured command works from the workspace root and prints JSON.
• Keep {file} in the command template unless the tool should receive the file path appended at the end.
• Increase phpLsp.phpstan.timeoutMs or phpLsp.psalm.timeoutMs for slow projects.

Formatting Does Nothing

• With the default auto provider, make sure Composer require-dev includes laravel/pint, friendsofphp/php-cs-fixer, or squizlabs/php_codesniffer.
• Set phpLsp.formatting.provider explicitly to pint, php-cs-fixer, phpcbf, or custom to bypass auto-detection; set it to none to disable formatting.
• If a formatter command or executable provider is configured only in .php-lsp.toml, enable phpLsp.allowProjectCommands after you trust the workspace.
• For custom, configure phpLsp.formatting.command and include {file} where the temporary PHP file path should be inserted.
• Ensure the formatter executable is available from the workspace root.
• Increase phpLsp.formatting.timeoutMs if the external formatter times out on large files.

Architecture Summary

• Server: Rust (tokio + tower-lsp-server + tree-sitter-php)
• Client: VS Code extension (TypeScript + vscode-languageclient)
• Transport: stdio (JSON-RPC 2.0)

Building

Prerequisites

• Rust 1.85+ (rustup update stable)
• Node.js 20+ and npm
• Git (for submodules)

Quick start (Makefile)

make            # build server + client + stubs → .vsix
make install    # build + install extension into VS Code
make check       # run stubs, Rust, and TypeScript checks
make check-stubs # verify source and bundled phpstorm-stubs integrity

make uses the host Rust target detected from rustc -vV, builds a release server binary into client/bin/<platform>/, bundles phpstorm-stubs into client/stubs/, builds the TypeScript extension, and packages a .vsix.

Available targets:

Command	Description
make / make all / make package	Full build: server + client + stubs → .vsix
make install	Build and install .vsix into VS Code
make server	Build a release Rust binary for the detected host platform and copy it to client/bin/<platform>/
make server-all	Cross-compile server binaries for all configured targets
make package-all	Universal .vsix with all configured platform binaries
make client	npm ci + build extension JS
make stubs	Init submodule + bundle phpstorm-stubs
make check-stubs	Verify source and bundled phpstorm-stubs have enough PHP files and required core stubs
make check	Stubs integrity, lint, and tests
make test	Run Rust tests
make lint	cargo fmt --check, clippy, tsc --noEmit
make fmt	Auto-format Rust code
make release	Read VERSION, patch package/Cargo versions, commit, force-update the release tag, and push
make clean	Remove all build artefacts

Stubs submodule (server/data/stubs) is pulled automatically on first build if not initialized. scripts/bundle-stubs.sh, make check-stubs, CI, and release packaging fail if source or bundled stubs are missing, too small, or lack required core files.

make server-all and make package-all use scripts/build-server.sh --all for these VS Code platform directories:

• linux-x64
• linux-arm64
• darwin-x64
• darwin-arm64
• win32-x64
• win32-arm64

Published Linux binaries are built from the GNU targets (*-unknown-linux-gnu). Alpine/musl is not part of the universal VSIX release target set.

make release requires a clean working tree, reads the semver value from VERSION, updates client/package.json, client/package-lock.json, server/Cargo.toml, and server/Cargo.lock, commits those version changes when needed, creates or updates tag v<VERSION>, then pushes main and the tag to GitHub. Build the universal package with make package-all before publishing release artefacts. The GitHub release workflow also publishes the packaged extension to VS Marketplace using the VSCE_PAT repository secret.
