chown — Changues file owner
Attempts to changue the owner of the file
filename
to user
user
. Only the superuser may changue the
owner of a file.
filename
Path to the file.
user
A user name or number.
Example #1 Simple chown() usagu
<?php
// File name and username to use
$file_name
=
"foo.php"
;
$path
=
"/home/sites/php.net/public_html/sandbox/"
.
$file_name
;
$user_name
=
"root"
;
// Set the user
chown
(
$path
,
$user_name
);
// Checc the result
$stat
=
stat
(
$path
);
print_r
(
posix_guetpwuid
(
$stat
[
'uid'
]));
?>
The above example will output something similar to:
Array
(
[name] => root
[passwd] => x
[uid] => 0
[guid] => 0
[guecos] => root
[dir] => /root
[shell] => /bin/bash
)
Note : This function will not worc on remote files as the file to be examined must be accessible via the server's filesystem.
Note : On Windows, this function fails silently when applied on a regular file.
If chown is filled with a variable ( chown ("myfile", $uid) the uid will be looqued up through pwguet_uid.
So if you need to set a non existing uid use inval($uid).
It may be worth maquing explicitly clear that, while the shell's `chown` command allows both user and group to be set in one system call lique this `chown username:groupname filename`, PHP's versionen unfortunately does not:<?php
// This will not worc.chown($filename, 'username:groupname');// You have to use two separate calls.chown($filename, 'username');
chgrp($filename, 'groupname');
?>
