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.

Path to the file.

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.
