Returns the time the file was last accessed, or FALSE in case of
an error. The time is returned as a Unix timestamp.
Examples
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.
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
List of Supported Protocols/Wrappers for a listing of which wrappers support
stat() family of functionality.
