I have a client who has a script that demands Zend 2.1 or better. I see that 1.2 is currently running under php 4.4.2 on my machine.

I also see that php 5.0.4 is available on yum.

Now I'm scared to upgrade either one given the amount of problems I've seen posted here.

Any recommendations? Can I just upgrade Zend to 2.1 and be OK? They have 3.0 available for php 5.1 on their site (and it claims to work with 4.04 or higher), but.. I dunno!

Advice please.

... pretty please...

Just install the latest Zend for the PHP version you have running or upgrade PHP and then install Zend for that version.

The key is to avoid upgrading PHP to a new version and not upgrade Zend with it. That will usually get you into trouble, unless it's just a minor upgrade (say: 4.4.1 -> 4.4.2).

So which Zend version would be appropriate for php 4.4.2? I currently have 1.3.0.

The Zend site says: "For PHP versions below 4.0.4, use the Zend Optimizer 1.2.0." So you can just install the latest version.

OK.. I'll give it a try. I assume if it fails horribly I can remove it and put 1.30 back.

Well, I put it in, and apache started hanging up horribly, and webmail attachments broke, so out it went.
