PHP 8.4 deprecation: (double) cast in RequestVerifier.php

[x-dragos]

Description

PHP 8.4 deprecated the (double) cast in favor of (float). This triggers a deprecation warning in production:

Non-canonical cast (double) is deprecated, use the (float) cast instead
in vendor/ratchet/rfc6455/src/Handshake/RequestVerifier.php on line 48

Location

src/Handshake/RequestVerifier.php, line 48:

public function verifyHTTPVersion($val): bool {
    return 1.1 <= (double)$val;
}

Fix

Replace (double) with (float):

public function verifyHTTPVersion($val): bool {
    return 1.1 <= (float)$val;
}
