I quit from the course

After many and many problems, i will quit of the course PHP of the code academy site. There’s errors all the time. When I make an wrong answer, the code, from the editor, stops all the time and even if I edit the answer correctly, the page don’t updates. Finally, an error appears, even if my code is right.
So, that’s it.
This problem happens a long time ago and I already had communicate to this site and nothing was maked. I have patience no more to wait for. Thanks.

The php course is scheduled for removal for a reason. If you really want to learn PHP, i would recommend finding another resource
