PHP script works on localhost but not on webserver

Question

I have this script.

On my localhost it works.

But when I upload it to the servers it reads only the html. Picture attached. Any idea of what it can be wrong? Maybe a php function on the server that might be disabled? What should I check? I have spoken with my webhost and he told me that I must know which function I need.

Answer 1

You can use ini_set and error_reporting to set the PHP Error Reporting to ALL and other error related ini settings. i.e:

<?php 
  error_reporting(E_ALL);
  ini_set('display_errors', '1');

Also, as mentioned in the comments, create a php file holding the phpinfo() command to see weather or not php is running on your server at all.

testphp.php

<?php
  phpinfo();

If you open yourwebsitesdomain.com/testphp.php and you do not see information on php running, contact your webhoster and tell him php is not working on the server.
