I was wondering this. I'm just pleased with PHP 4 (I didn't know there was much difference!) but I read all that about 5 and I was wondering which one most people used. I've also heard of PHP 6, but haven't heard much about it.

I use PHP 4 in my projects but I'm still learning and I don't need all that OOP stuff (the thought of a class makes me go queesy !

PHP6? That's not released yet.. well.. from what I know. It's planned to release this summer.

PHP5 is my choice.. secure, fast, and compatible with many scripts.

Yep: PHP5 is my preference, but I still end up developing for PHP4 as I'm all but guaranteed that my clients' servers will have it installed. PHP5 (while getting better) is still hit-and-miss unfortunately

I'm looking forward to PHP6, if only for the complete removal of register_globals and all the newbie questions that go with it

I'm doing PHP5 everywhere, and for the last 2 years.

but I still end up developing for PHP4 as I'm all but guaranteed that my clients' servers will have it installed

For me, it's quite simple.
for every script I have already made, I tell them that those scripts need php5, and until now, every one have got PHP5 installed for they server.

Oops! I should spend more time looking at their website! Can vbulletin edit polls?

i think that the question is a little off.
There is no discution that php5 is better then php4 ( they wouldnt have released if it was not )
It's just a matter of what version do you like / use more .

I would if I could A lot of the people that buy scripts from me have already set themselves up with their server and a lot of the time they went the 'cheap host' option... a lot of which don't do PHP5 yet.

For those people that are setting up they're own environments it's all good but unfortunately, it's the cheap hosted sites that are a problem for me and I'd rather go for the lowest common denomination when it comes to them and 'non-custom' scripts.

True...
In the mean time, every jobs I've done covered full sites, and rather complicated ones.
Last job I did earned me 3'000 $, and I often do upgrades or revises / consulting on existing scripts.
Sometime re-implement them to add further fonctionnalities or better performances.
So, most of my clients are not the "cheap host" regular.

My most regular client runs a 20 computers. clustered network (3 file servers, 7 db and 10 web with lighthttp + apache as frontend, with a few failover comp. in case of problems) to serve every sites he have (myspace related, and doing quite well, I must say...)

Not quite the "small fish" :-p

PHP 4 is the best

tripy: agreed. Unfortunately about half my cash comes from 'complete' jobs and the other half comes from 'off-the-shelf' type scripts that I've written. Not that I'm complaining... I may have to do them in PHP4, but once it's done, it's done.

That's my 'decider': PHP5 for 'complete, once off' type jobs, PHP4 for code that I can just continue to sell with no more work. PHP4 is the 'con' while 'residual/passive income' is the 'pro'

agreed. Unfortunately about half my cash comes from 'complete' jobs and the other half comes from 'off-the-shelf' type scripts

I have some ideas in my mind, and I think too that I will go taht way.
It's true that there are just too many php4 hosts that don't want to upgrade.
But's a shame....

I like php5 more than php4 because of extra oo support. never got the chance to play around with v6 yet.

We have been working on PHP 5 and it gives better performance.
