1.The first thing we need to do is check a couple of PHP settings. The easiest way to do this is with a phpinfo file. If you don't know how to create a phpinfo file, you can find instructions here.
2.Now that you have a php info file, upload it to your website's public_html directory and view it in your browser by typing http://www.yoursite.com/phpinfo.php in your address bar. You want to find/verify the following in your phpinfo.php file:
[ol]Your PHP version Thread Safety is disabled enable_dl is set to on The path to your extension_dir Path to your php.ini file
[/ol]
3.Now connect to your webserver using your favorite SSH client and login as root.
4.Create a new working directory then change directories:
you will see a bunch of files named phpshield.4.3.lin to phpshield.5.2.lin. What we want to do here is find the phpshield file with the number that matches your PHP version. You can find your PHP version at the very top of your phpinfo file from earlier.
8.Now we need to copy the appropriate phpshield loader file to your PHP extensions directory.
