Answer 1

Since you are doing a regression from 5.4 to 5.2, read the list of new features from 5.3 and 5.4. If you are using any of them, you will need to remove them:

• http://www.php.net/manual/en/migration53.new-features.php
• http://www.php.net/manual/en/migration54.new-features.php

I did a regression like that, and the most painful part was that I had to stop using anonymous functions .

Also, it meant to change from arrays declared like $a = [1,2]; to $a = array(1,2); .

Well, read the links and see how much you'll be missing.
