Re: [PHP] Re: Noob stuff - Zend/Opcode/Cache/Optimizer
Hi, In general, the Zend Engine is an integral part of PHP (the engine so to speak of PHP). It's open source, and is developed as part of PHP generally speaking by the same community (or maybe specific people in that community). Zend Server (incl. Zend Server CE) is a Zend (the company) product. A simplistic description of it would be that it's a commercial distribution of PHP with some extra components - Optimizer+ being one of them. The two are very different things, and should not be confused :) My specific comments follow: On 29/12/09 17:00 PM, Daniel Kolbo wrote: Shawn McKenzie wrote: Daniel Kolbo wrote: Hello, I'm missing some unifying piece of the zend/php puzzle...

I am under the impression that I need to install the Zend Server Community Edition (ZSCE) to get the zend optimizer+. I thought PHP came with the zend engine...why do i now have to download this ZSCE just to add a component to the engine i already have? 1) Is there a way to turn on zend optimizer+ component (like in php.ini zend extension) without having to install ZSCE? It is an extension available on the Zend download page. Unlike Optimizer, Optimizer+ is not available as a separate download, but only as part of Zend Server (and ZSCE). You could technically just download ZSCE, grab the .so / .dll of Optimizer+ and add it to any other compatible (same version, similar build) PHP setup. It may or may not work, and generally at Zend we only test Optimizer+ as part of Zend Server. 1.2) If i have to install the ZSCE stack, wouldn't this effectively be adding another engine on my machine? You would effectively be adding another PHP installation, so the answer is technically yes. The Engine is not separate from PHP, so it's not another Engine - it's another installation of PHP. Yes, it is a install of PHP with alot of other stuff bundled in. So it depends upon what you need and if you want to install/configure PHP yourself with all of these additions, or if you just want to install the Zend server. Hello Mr. McKenzie, Thanks for the response. I do not see zend optimizer+ on: http://www.zend.com/en/downloads/ There is a zend optimizer download link, but this is different than zend optimizer+. My understanding is the former facilitates with the use of zend gaurd while the latter optimizes the opcode. I want the latter component. That is generally true - they both do optimizations, while Optimizer also loads Guard-encoded files and Optimizer+ also does opcode caching after optimizing it. If you're looking for performance Optimizer+ is the one you're looking for. That said, it is not available as a separate download - only as part of ZS/CE. Where does one obtain the zend optimizer+ component? (I spent the better part of my saturday trying to find it). I ended up installing the zend server community edition to see how it configured its own apache and php installs in the httpd.conf and php.ini as a way to shed some light on to my understanding. The zend server is using different libraries then the standard php install. I could try to mimic the behaviour of the zend server configuration with my original php configuration; however, I'm a bit concerned about only grabbing partial components...maybe i don't need to be so worried. Maybe this plan isn't even possible. As I mentioned this might or might not work, depending on what PHP exactly you'll try to run it on. BTW why not just use ZSCE? Which incompatibilities did you encounter? Cheers, Shahar. I guess i was expecting to google, 'install zend optimizer+ component' and find gogles of howtos. Because i don't see this, it makes me wonder if i'm trying to do something i oughta not... My question boils down to: How do I extend my current php install to add a component (zend optimizer+) to my current php install?

Thanks, dK ` I'm really not sure what the + designation is for, they may have changed the way things work since I last used the optimizer. The Zend Optimizer used to be a byte code optimizer/cacher that also allowed you to run Zend Guard encrypted apps that you were authorized to use. Zend Guard you need to buy and it allows you to encrypt your apps. -- Thanks! -Shawn http://www.spidean.com -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
