PHP manual

Description

When you need information about a file’s path, you use pathinfo. You give it the path that you want to check. If you specify the element you want back, then it returns just that element in a string; else it returns an associative array that contains the following elements:

• dirname
• basename
• extension (if any)
• filename

Parameters

pathinfo

The path to be evaluated and parsed.

specific_element

optional The specific element you want to receive back instead of the entire associative array. If you want this option, then pass in one of these constants: PATHINFO_DIRNAME, PATHINFO_BASENAME, PATHINFO_EXTENSION, PATHINFO_FILENAME.

Return Values

Returns a string for the specific element you requested or, if none is requested, then you get an associative array back.
