You need to find out what O/S and version you are using. Try:
gcc -v from Telnet/SSH and it should produce an output similar to this: [admin@raq557 admin]$ gcc -v
Reading specs from /usr/lib/gcc-lib/i386-redhat-linux/egcs-2.91.66/specs
gcc version egcs-2.91.66 19990314/Linux (egcs-1.1.2 release)

Obviously if you are on a Windows based server you are not going to be able to do this - therefore you'll want the Windows NT/2K (for PHP 4.0.4).

Importantly, you'll probably need to upgrade your version of php - or find an older version of Zend which will work for 4.03. Im no pro - this is just the obvious stuff, someone with more talent around here might be able to help you out more - this would be a good start though :)

Ops for about the OS, I'm using RedHad 7.1

[Martz]

You will probably want one of these 2 - make sure someone else clarifies/confirms this before you dive in and install it :)

Linux libc5 (for PHP 4.0.3)
or
Linux glibc2.1 (for PHP 4.0.3)

It may already be installed - have you put:
<?php phpinfo() ?>
in a php file and run it? It should say if you have zend or gzip on your system.

In my experience, unless you're using caching software, the benefits of using the Optimizer are virtually negligible when using vB and moderate hardware. The speed improvement of the compiled script is easily offset by the time taken to to parse and optimize it. Unfortunately, the only caching software that works with the Zend Optimizer, is their own that sells for $2,500.

$2,500 wow that is way too expensive!

Are there any Caching software that is good and cost less or better still free?

APC at http://apc.communityconnect.com/
or
afterBurner at http://bwcache.bware.it/

Both say they plan to support the Zend optimizer some time in the future. The APC version seems to be updated more often.

I have successfully used both at one time or another.

I would recommend against using the Zend "Optimizer".... in my experience it will actually slow things down. Here's a good benchmark page showing different php cache tools: http://www.dynamicwebpages.de/bench/cacheoverview.html

I have used both APC Cache and PHP Accelerator ( http://www.php-accelerator.co.uk/ ) and both work pretty well.

Using APC, having no problems with it and the speed increase was definetly discernable.

Haven't seen a leak since installing it. I'm using the latest version.

I use bware_cache - seems fine for me - we got huge memory leaks with APC like others here :)

[eva2000]

If so I'd like to install php accelerator and uninstall zend but it came with my cpanel machine. Any ideas on if I should and how to uninstall/install? thank you.
