upgrade to php5, any issues?

[munkynpunky]

hey,

my server provider is going to recompile php for me to add mcrypt, however they have to upgrade it to the latest version of php, rather than 4..

will there be any real issues i should look out for?

I use Plesk 8.1.1 too

Not really. It's mostly backwards-compatible.

The issues, if any, will likely be similar to using any other server (with php 4), based on general settings, like error reporting, register globals, etc.

the only issue is separation of mysql client library, but if you use prepackaged/precompiled/windows binary- there shouldn't be a problem
