Yourself PHP (PHP, Exploit, XSS)

Yourself PHP
Your mission is to inject <script>alert(1);</script> into this script, and make it popup a javascript alert.
The checkit() function tests your injected string for a few static solutions.
Please try to use as less characters as possible and inject the exact same string as above.

Note: This challenge is simulated, and does only check for a few static solutions.

So even if you inject the right code, it will not execute anymore.
