php 5.2.17 vs php 5.3.13?

[gwmbox]

Does anyone know if there is anything in php 5.2.17 that no longer works in 5.3.13?

I am trying to work this out via the change-log and from what I can see it covers everything that 5.2.17 did plus more... but I can't work out if there is something in 5.2.17 that is no longer works in 5.3.13... at least so far...

My reason for requesting this is our host is still using 5.2.17 and I need to have php 5.3.x. Yes I can move to another server which is fine but if there is no missing items then maybe they can update the existing server.

Cheers

Sometimes they do change subtle usages. That's rare though. It's noted on PHP.net under each function individually but that might be hard to figure out-- if you do get an idea you could check it that way. Or, yes, the changelogs.

The other possibility is that some feature has become deprecated. But that won't stop it from working. It will just give an error.

Turn error reporting on fully then see if you get any messages. That's where you'd have to start.

If not, then systematically deconstruct the script until you find it-- comment out sections, remove includes, etc., until you find the problematic area. Of course it's a lot of work, but there's no easy answer to that.

Also, if you haven't already, email your host and ask them to upgrade your version of PHP.
Any decent host should be able to do so on an account-by-account basis, and most will (not always the "bleeding edge" version, but 5.3 has been around for a while - it shouldn't be a problem).
