使用PHP Chmod文件

Question

Let's say i allow the user to upload a file to my website.

Using php, i am giving this an address,

$pic = '/~start/B7/images/456.jpg'

how can i chmod this file to make it readable using php? I have tried chmod ($pic, 0705); but that doesn't seem to work. Thanks for the help.

Answer 1

The exec function will allow you execute shell commands. Try this:

<?php
 exec("chmod $pic 0705");
?>
