What PHP 5+ incompatibilities have you faced?
I haven't found much specific information on this. Therefore I did a test on a test server and found that it does have some incompatibilities. I thought it will be nice if anyone using it to share their experiences so that those who's considering the upgrade can make an informed choice.
1. GD library Gif library seems to be messed up. GD functions code seems to end up messing up the picture. This can be fixed by converting all gif to true 256 colour.
2. Blogging software like B2Evolution, Wordpress all started sputtering with Mysql errors.
For those who had done their testing, what do you have to add? Thank you.
