Changing Owner/Group ID In PHP

Question

In my client's ftp the old files have 3002 3000 value in owner/group column.

But when I upload a new page it has 3002 3002 and I can't access this file.

When I try to load this new page it displays error:

NetworkError: 500 Internal Server Error

Why this happen?

If there is any php code to change the 3002 3002 to 3002 3000?

How can I change owner/group value ? Can I change the owner/group Id using any php code?

I already used chown() function , but nothing will happen the owner/group column value in ftp still displaying 3002 3002

Answer 1

<?php

// File name and username to use
$file_name= "test.php";
$path = "/home/sites/public_html/login/" . $file_name ;
$user_name = "root";

// Set the user
chown($path, $user_name);

// Check the result
$stat = stat($path);
print_r(posix_getpwuid($stat['uid']));

?>

It will return something like :-

Array
(
    [name] => root
    [passwd] => x
    [uid] => 0
    [gid] => 0
    [gecos] => root
    [dir] => /root
    [shell] => /bin/bash
)

For Changing a file's group :-

  <?php
     $filename = 'file.txt';
     $format = "%s's Group ID @ %s: %d\n";
     printf($format, $filename, date('r'), filegroup($filename));
     chgrp($filename, 8);
     clearstatcache(); // do not cache filegroup() results
     printf($format, $filename, date('r'), filegroup($filename));
  ?>
