A PHP file should begin with <?php. <!-- is an HTML opening comment tag.

A PHP file:

<?php
  $arr = array(
    $key => $val
  );

And HTML file with a comment:

<!-- This is a comment -->
<div>An element</div>

Hello!

You use "=>" in an associative array to assign a value to the key. The extra "--" is either an old php close tag, or a typo you made.

Just try removing the two "-" and you should be ok, assuming all else is correct. Like this:

$array = array(
    '0' => '5',
    '1' => '2',
    '2' => '0',
    '3' => '3',
    '4' => '1');

The Editor i was using was auto commenting my PHP code. I pasted the code from an old program that I was using, so I knew that it worked.

Thanks you both for your help.

I will need to not find a way to upload a PHP file to this server directly.

Thanks Again.
