[SOLVED] Why are there so many php4 servers still out there?

Hello,

 

Why are there still so many web servers out there with php4 installed?  I'm pretty sure that php4 is not being supported by userland any more and php6 has been released.  So why are the server admins reluctant to upgrade? Is there there any compatibility issue?

Yes, some php4 code will break in php5.  I use virtualmin for my hosting platform and it lets me use php4 or php5 (and now php6) set per virtual host, but I don't think many others do that.

Theres actually not too many compatability issues moving from php4 - php5. The main issue is different configurations. eg; register_globals

 

I guess alot of hosts are scared of breaking clients code.

 

Oh and ps. PHP6 is still a whiles off yet. If by released you mean available, then of course, you can get it. I wouldn't use it on any production servers however.

You worded it better.  Its not the actual code, but the settings.  Like magic quotes.  A lot of code relies on this being set to on because lazy programmers use stuff like this.  If you set it to off, which will be standard in php6, it will break the code that relies on it being on.
