function drupal_dirname in Drupal 7

Same name and namespace in other branches

1. 8 core/includes/file.inc \drupal_dirname()

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.
