WampServer

My host has PHP 5.1.2 and MySQL 4.1.x still. Is there a way I can just use MySQL 4.1.x instead of the new 5.x?

Does it even matter? Will my 5.x database output workw th 4.1.x server?

I also had this problem, i had MySQL 5 on my computer and 4 on the web server, if it's only for the "normal" queries it doesn't really matter (like insert, update, delete) (if i remember right)

otherwise, if you really want MySQL 4.1.x, you maybe should install apache php and mysql yourself, it's not that hard, but if you have some hesitation, just install mysql 4.1.x and in case of need, disable the one from wamp and start the 4.1.x, it's complicated, but that's how it will be if you reaaaaaally want to have mysql 4.1.x and wamp....

(Wamp5, isn't it like "Windows apache mysql php" and the 5 because mysql and php are at version 5?)

Just make sure you do not use new MySQLi extention, as it in only supported newest version of mysql and php
