pathinfo

Returns information about a file path

Syntax

pathinfo ( string $path [, int $options = PATHINFO_DIRNAME | PATHINFO_BASENAME | PATHINFO_EXTENSION | PATHINFO_FILENAME ] ) : mixed

Parameters

path

The path to be parsed.

options

If present, specifies a specific element to be returned; one of PATHINFO_DIRNAME, PATHINFO_BASENAME, PATHINFO_EXTENSION or PATHINFO_FILENAME. If options is not specified, returns all available elements.

Return

If the options parameter is not passed, an associative array containing the following elements is returned: dirname, basename, extension (if any), and filename. If options is present, returns a string containing the requested element.

Note: If the path has more than one extension, PATHINFO_EXTENSION returns only the last one and PATHINFO_FILENAME only strips the last one.

Note: If the path does not have an extension, no extension element will be returned.

Note: If the basename of the path starts with a dot, the following characters are interpreted as extension, and the filename is empty.
