mixed pathinfo ( string $path [, string $specific_element ] );
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:
- extension (if any)
- The path to be evaluated and parsed.
- 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:
Returns a string for the specific element you requested or, if none is requested, then you get an associative array back.
