PHP Version Confict

[nex1234]

I wrote several pages of script using PHP version 4.3.10.  I now need to update and run the script on PHP version 5.2.5.  However, after installing the newer version some of the script works and some does not.  There a lot of code so I won't post at this time.  But I was wondering if anyone could provide maybe a basic explanation of the possible conflicts/causes for errors.

Thanks

you may have extensions that were installed on php 4 that are not on in php 5. Check all your extension or get the ones you need and activate them. One example is mysql. mysql extension is not on by default in php 5 you have to uncomment the line in php.ini and make sure the extension is in the extensions folder.

Using short tags "<?" instead of long tags "<?php"

 

Assuming that register_globals are enabled.

 

If you use classes, there are some differences.

 

Your best bet is to check the fine manual.

Turning on full php error reporting (E_ALL) and setting display_errors = On in php.ini will get php to help by pointing out problems it finds.
