<?php
/*
   Prototype: int fileatime ( string $filename );
   Description: Returns the time the file was last accessed, or FALSE
     in case of an error. The time is returned as a Unix timestamp.

   Prototype: int filemtime ( string $filename );
   Description: Returns the time the file was last modified, or FALSE
     in case of an error.

   Prototype: int filectime ( string $filename );
   Description: Returns the time the file was last changed, or FALSE
     in case of an error. The time is returned as a Unix timestamp.

   Prototype: bool touch ( string $filename [, int $time [, int $atime]] );
   Description: Attempts to set the access and modification times of the file
     named in the filename parameter to the value given in time.
