The Variables::getMemberProperties() method is based on and inspired by the method of the same name in the PHPCS native PHP_CodeSniffer\Files\File class. Also see {@see \PHPCSUtils\BackCompat\BCFile}.

Properties

$phpReservedVars

List of PHP Reserved variables.

public static array $phpReservedVars = [ '_SERVER' => true, '_GET' => true, '_POST' => true, '_REQUEST' => true, '_SESSION' => true, '_ENV' => true, '_COOKIE' => true, '_FILES' => true, 'GLOBALS' => true, 'http_response_header' => false, 'argc' => false, 'argv' => false, // Deprecated. 'php_errormsg' => false, // Removed PHP 5.4.0. 'HTTP_SERVER_VARS' => false, 'HTTP_GET_VARS' => false, 'HTTP_POST_VARS' => false, 'HTTP_SESSION_VARS' => false, 'HTTP_ENV_VARS' => false, 'HTTP_COOKIE_VARS' => false, 'HTTP_POST_FILES' => false, // Removed PHP 5.6.0. 'HTTP_RAW_POST_DATA' => false, ]

The array keys are the variable names without the leading dollar sign, the values indicate whether the variable is a superglobal or not.

The variables names are set without the leading dollar sign to allow this array to be used with array index keys as well. Think: '_GET' in $GLOBALS['_GET'].}

Methods

getMemberProperties()

Retrieve the visibility and implementation properties of a class member variable.

public static getMemberProperties(File $phpcsFile, int $stackPtr) : array

Main differences with the PHPCS version:

  • Removed the parse error warning for properties in interfaces. This will now throw the same "$stackPtr is not a class member var" runtime exception as other non-property variables passed to the method.
  • Defensive coding against incorrect calls to this method.
Parameters
$phpcsFile : File

The file being scanned.

$stackPtr : int

The position in the stack of the T_VARIABLE token to acquire the properties for.

throws
RuntimeException

If the specified position is not a T_VARIABLE token.

throws
RuntimeException

If the specified position is not a class member variable.

Return values
array

Array with information about the class member variable. The format of the return value is:

array(
  'scope'           => string,  // Public, private, or protected.
  'scope_specified' => boolean, // TRUE if the scope was explicitly specified.
  'is_static'       => boolean, // TRUE if the static keyword was found.
  'type'            => string,  // The type of the var (empty if no type specified).
  'type_token'      => integer, // The stack pointer to the start of the type
                                // or FALSE if there is no type.
  'type_end_token'  => integer, // The stack pointer to the end of the type
                                // or FALSE if there is no type.
  'nullable_type'   => boolean, // TRUE if the type is nullable.
);

isPHPReservedVarName()

Verify if a given variable name is the name of a PHP reserved variable.

public static isPHPReservedVarName(string $name) : bool
Parameters
$name : string

The full variable name with or without leading dollar sign. This allows for passing an array key variable name, such as '_GET' retrieved from $GLOBALS['_GET'].

Note: when passing an array key, string quotes are expected to have been stripped already. Also see: {@see \PHPCSUtils\Utils\TextStrings::stripQuotes()}.

isSuperglobal()

Verify if a given variable or array key token points to a PHP superglobal.

public static isSuperglobal(File $phpcsFile, int $stackPtr) : bool
Parameters
$phpcsFile : File

The file where this token was found.

$stackPtr : int

The position in the stack of a T_VARIABLE token or of the T_CONSTANT_ENCAPSED_STRING array key to a variable in $GLOBALS.

Return values
bool

TRUE if this points to a superglobal; FALSE when not.

Note: This includes returning FALSE when an unsupported token has been passed, when a T_CONSTANT_ENCAPSED_STRING has been passed which is not an array index key; or when it is, but is not an index to the $GLOBALS variable.

isSuperglobalName()

Verify if a given variable name is the name of a PHP superglobal.

public static isSuperglobalName(string $name) : bool
Parameters
$name : string

The full variable name with or without leading dollar sign. This allows for passing an array key variable name, such as '_GET' retrieved from $GLOBALS['_GET'].

Note: when passing an array key, string quotes are expected to have been stripped already. Also see: {@see \PHPCSUtils\Utils\TextStrings::stripQuotes()}.
