PHP 4 to 5

I have read in some forums about the concerns that PHP 5 might break old PHP 4 scripts. Like I said, I have been using PHP5 since Beta 2 and I haven’t had a problem. There are some issues however which some more obscure things that could go wrong. So in case anyone is interested you can read Zend’s Backwards Incompatible Changes.
