ckeditor - what difference between syntax php in php version 5.4.16 dengan 5.2.17? -

i made website php version 5.4.16, learning hosted sites support 5.2.17. , it's make trouble ckeditor, can't post html or else.

anyone knows syntax in ver 5.4.16 doesn's support in ver 5.2.17 ? please share know. help.

since doing regression 5.4 5.2, read list of new features 5.3 , 5.4. if using of them, need remove them:

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

i did regression that, , painful part had stop using anonymous functions.

also, meant change arrays declared $a = [1,2]; $a = array(1,2);.

well, read links , see how you'll missing.
