fileatime -- Gets last access time of file

Description

int fileatime ( string filename )

Returns the time the file was last accessed, or FALSE in case of an error. The time is returned as a Unix timestamp.

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.

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));
}

?>
