function drupal_dirname

drupal_dirname($uri)

Gets the name of the directory from a given path.

PHP's dirname() does not properly pass streams, so this function fills that gap. It is backwards compatible with normal paths and will use PHP's dirname() as a fallback.

Compatibility: normal paths and stream wrappers.

Parameters

$uri: A URI or path.

Return value

A string containing the directory name.
