                                   filemtime

   (PHP 3, PHP 4 )
   filemtime -- Gets file modification time

Description

   int filemtime ( string filename)

   Returns the time the file was last modified, or FALSE in case of an
   error. The time is returned as a Unix timestamp, which is suitable for
   the date() function.

     Note: The results of this function are cached. See clearstatcache()
     for more details.

     Tip: As of PHP 5.0.0 this function can also be used with some url
     wrappers. Refer to Appendix I for a listing of which wrappers
     support stat() family of functionality.

   This function returns the time when the data blocks of a file were
   being written to, that is, the time when the content of the file was
   changed.

   Example 1. filemtime() example
   <?php
   // outputs e.g.  somefile.txt was last modified: December 29 2002
   22:16:23.
   $filename = 'somefile.txt';
   if (file_exists($filename)) {
       echo "$filename was last modified: " . date ("F d Y H:i:s.",
   filemtime($filename));
   }
   ?>

   See also filectime(), stat(), touch(), and getlastmod().
