(PHP 4, PHP 5, PHP 7, PHP 8)
chown — Changes file owner
Description
chown(string
$filename, string|int $user): bool
Attempts to change the owner of the file filename
to user user. Only the superuser may change the
owner of a file.
Parameters
-
filename -
Path to the file.
-
user -
A user name or number.
Return Values
Returns true on success or false on failure.
Examples
Example #1 Simple chown() usage
<?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);
// Check the result
$stat = stat($path);
print_r(posix_getpwuid($stat['uid']));
?>
The above example will output something similar to:
Array
(
[name] => root
[passwd] => x
[uid] => 0
[gid] => 0
[gecos] => root
[dir] => /root
[shell] => /bin/bash
)
Notes
Note: This function will not work 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.
