stat
STAT(3) 1 STAT(3)stat - Gives information about a fileSYNOPSIS
array stat (string $filename)
DESCRIPTION
Gathers the statistics of the file named by $filename. If $filename is a symbolic link, statistics are from the file itself, not the sym-
link.
lstat(3) is identical to stat(3) except it would instead be based off the symlinks status.

* On Windows this will always be 0.
** Only valid on systems supporting the st_blksize type - other systems (e.g. Windows) return -1.
In case of error, stat(3) returns FALSE.
Note
Because PHP's integer type is signed and many platforms use 32bit integers, some filesystem functions may return unexpected results
for files which are larger than 2GB.
ERRORS /EXCEPTIONS
Upon failure, an E_WARNING is emitted.
EXAMPLES
Example #1
stat(3) example
<?php
/* Get file stat */
$stat = stat('C:phpphp.exe');
/*
* Print file access time, this is the same
* as calling fileatime()
*/
echo 'Access time: ' . $stat['atime'];
/*
* Print file modification time, this is the
* same as calling filemtime()
*/
echo 'Modification time: ' . $stat['mtime'];
/* Print the device number */
echo 'Device number: ' . $stat['dev'];
?>
Example #2
Using stat(3) information together with touch(3)
<?php
/* Get file stat */
$stat = stat('C:phpphp.exe');
/* Did we failed to get stat information? */
if (!$stat) {
echo 'stat() call failed...';
} else {
/*
* We want the access time to be 1 week
* after the current access time.
*/
$atime = $stat['atime'] + 604800;
/* Touch the file */
if (!touch('some_file.txt', time(), $atime)) {
echo 'Failed to touch file...';
} else {
echo 'touch() returned success...';
}
}
?>
NOTES
Note
Note that time resolution may differ from one file system to another.
Note
The results of this function are cached. See clearstatcache(3) for more details.
Tip
As of PHP 5.0.0, this function can also be used with some URL wrappers. Refer to "Supported Protocols and Wrappers" to determine
which wrappers support stat(3) family of functionality.
