fileatime
(PHP 4, PHP 5)
fileatime — Gets last access time of file
Description
int fileatime
( string $filename
)
Gets the last access time of the given file.
Parameters
-
filename
-
Path to the file.
Return Values
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
$filename = 'somefile.txt';
if (file_exists($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.
