Example#1 fileatime() example

<?php

// outputs e.g.  somefile.txt was last accessed: December 29 2002 22:16:23.

$filename 'somefile.txt';
if (
file_exists($filename)) {
    echo 
"$filename was last accessed: " date("F d Y H:i:s."fileatime($filename));
}

?>

Notes

Note: The atime of a file is supposed to change whenever the data blocks of a file are being read. This can be costly performance-wise when an application regularly accesses a very large number of files or directories.
Some Unix filesystems can be mounted with atime updates disabled to increase the performance of such applications; USENET news spools are a common example. On such filesystems this function will be useless.

Tip

As of PHP 5.0.0 this function can also be used with some URL wrappers. Refer to List of Supported Protocols/Wrappers for a listing of which wrappers support stat() family of functionality.
