PHP4 or PHP5?

[Sunny.]

I always use PHP 4 =]

[Heinous]

i use php5, just as i like the better oop features it brings. Other than some exstra stuff though theres VERY little difference between them, i was able to move thybag in its entirety from php4 to 5 with only a few incredibly minor edits and on most parts none at all.
Becuse php5 has everything of 4 pretty much and more, it seems kinda pointless keeping 4 around, apparnly php4 is still installed on the server i use in addition to 5 but i see no reason to revert "/

Pretty much the exact same for me.

I use php5 primarily (testing locally = php5, testing on my host = php5), but at the same time I have access to php4 on both as well, but I see no reason to stick to php4 anymore.

I say start using php5.
