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));
}

Notes
Note: 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: 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.

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.
