public function FileSystem::realpath

public FileSystem::realpath($uri)

Resolves the absolute filepath of a local URI or filepath.

The use of this method is discouraged, because it does not work for remote URIs. Except in rare cases, URIs should not be manually resolved.

Only use this function if you know that the stream wrapper in the URI uses the local file system, and you need to pass an absolute path to a function that is incompatible with stream URIs.

Parameters

string $uri: A stream wrapper URI or a filepath, possibly including one or more symbolic links.

Return value

string|false The absolute local filepath (with no symbolic links) or FALSE on failure.

Overrides FileSystemInterface::realpath

Code

public function realpath($uri) {
  // If this URI is a stream, pass it off to the appropriate stream wrapper.
  // Otherwise, attempt PHP's realpath. This allows use of this method even
  // for unmanaged files outside of the stream wrapper interface.
  if ($wrapper = $this->streamWrapperManager->getViaUri($uri)) {
    return $wrapper->realpath();
  }

  return realpath($uri);
