How will you check and confirm that your server is using suPHP?

It’s very simple to verify this. Have a simple ‘php info’ script.

Create a file named ‘phpinfo.php’ under the public_html of your domain

Insert the following code:

<?php
phpinfo();
?>

Access the file in your browser using the link https://yourdomain.com/phpinfo.php

At the top section search the line ‘Server API’.
If you see’CGI’ then your account is hosted on a server with suPHP.
If it shows ‘apache’ then you are NOT on a suPHP server.
