filemtime

Description

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.

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)); } ?>
