PHP

Changes file owner


chown

(PHP 4, PHP 5)

chownChanges file owner

Description

bool chown ( string $filename , mixed $user )

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: When safe mode is enabled, PHP checks whether the files or directories being operated upon have the same UID (owner) as the script that is being executed.
