(PHP 4, PHP 5)
fileatime — Gets last access time of file
Gets the last access time of the given file.
Path to the file.
Returns the time the file was last accessed, or FALSE in case of an error. The time is returned as a Unix timestamp.
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));
}
?>
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.

Fra og med PHP 5.0.0 kan denne funktion også bruges med nogle URL wrappers. Se List of Supported Protocols/Wrappers for en liste over hvilke wrappers understøtter stat() familiens funktionalitet.
