What difference are there in PHP 5 compared with PHP 4?. The reason I am asking is that the host for my website has upgraded to PHP 5 and some of the PHP stuff I downloaded only works in PHP 4.
Is it a major task to change something to work in PHP 5? (As it is a free, the company is unlikely to make the changes, at least at the moment, to get this to work).
Sorry about being a bit vague.
