Here we are solving a basic problem faced by a beginner web developer in PHP i.e. How to change file owner in PHP .

Sample code

<?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"]));

?>

chown attempts to change the owner of the file filename to user. Only the superuser may change the owner of a file.

Syntax

bool chown ( string $filename , mixed $user )

Parameters

1) filename

Path to the file.

2) user

A user name or number.

Note: This function will not work on remote files as the file to be examined must be accessible via the server's filesystem.
