Description
int
filectime ( string filename )
Returns the time the file was last changed, or FALSE in case of
an error. The time is returned as a Unix timestamp.
Note: In most Unix filesystems, a file is considered
changed when its inode data is changed; that is, when
the permissions, owner, group, or other metadata
from the inode is updated. See also
filemtime() (which is what you want to use
when you want to create "Last Modified" footers on web pages) and
fileatime().
Note also that in some Unix texts the ctime of a file is
referred to as being the creation time of the file. This is wrong.
There is no creation time for Unix files in most Unix filesystems.
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
Appendix M for a listing of which wrappers support
stat() family of functionality.
Example 1. A filectime() example <?php
// outputs e.g. somefile.txt was last changed: December 29 2002 22:16:23.
$filename = 'somefile.txt';
if (file_exists($filename)) {
echo "$filename was last changed: " . date("F d Y H:i:s.", filectime($filename));
}
