fileatime() example
php
<?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.
