(PHP 4, PHP 5)
filectime — Gets inode change time of file
Gets the inode change time of a file.
Path to the file.
Returns the time the file was last changed, or FALSE in case of an error. The time is returned as a Unix timestamp.
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));
}
?>
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.
Note: 시간 정밀도는 각각 파일 시스템에 따라 다를 수 있습니다.
