Code

public static function invalidate($pathname) {
  clearstatcache(TRUE, $pathname);

  // Check if the Zend OPcache is enabled and if so invalidate the file.
  if (function_exists('opcache_invalidate')) {
    opcache_invalidate($pathname, TRUE);
  }

  // If apcu extension is enabled in PHP 5.5 or greater it emulates apc.
  // This is to provide an easy upgrade path if you are using apc's user
  // caching however the emulation does not extend to opcode caching.
  // Therefore we need to check if the function exists as well.
  if (extension_loaded('apc') && function_exists('apc_delete_file')) {

    // apc_delete_file() throws a PHP warning in case the specified file was
    // not compiled yet.
    // @see http://php.net/manual/en/function.apc-delete-file.php
    @apc_delete_file($pathname);
  }
