PHP optimization, buffering, compression_PHP tutorial

This article proposes practical solutions for the optimization, buffering and compression of php(as the current mainstream development language)

As a popular Web programming language, php(as the current mainstream development language) The biggest advantage of today's mainstream development languages) is speed. php(as the current mainstream development language)4 has done a very good job in this regard, and you can hardly find a scripting programming language that is faster than it. But if your application load is heavy and your bandwidth is relatively small, or there are other bottlenecks that affect your server performance, then you might as well try some of the prescriptions I have prescribed for you to see if they are effective.


1. Code Optimization

When it comes to code optimization, maybe you think of neat and clear code, but the meaning of this article is not that, because if you want to seek speed , it is necessary to make corresponding adjustments to the source code of php(as the current mainstream development language). Generally speaking, redundant comments are removed to make the code unreadable. But for a programmer with good qualities, this is simply incredible. Fortunately, Zend Technologies has released the Zend optimization engine to help you do this. It's free now, but you must follow the Zend Optimizer license. This product can optimize the intermediate code generated by the engine.

Installing this engine is relatively simple. After downloading the version corresponding to the platform, unzip the compressed file, and then add the following two lines to the php(as the current mainstream development language).ini file OK, restart the web server and you're done.

zend_optimizer.optimization_level=15
zend_extension="/path/to/ZendOptimizer.so"
zend_loader.enable=Off

If it is a Win32 platform, it should be:

zend_optimizer.optimization_level=15
zend_extension_ts="C:path o endOptimizer.dll"
zend_loader.enable=Off

Ah! That's not a mistake? Why three lines? Actually the third line is optional. Because it seems that turning off zend_loader can improve the speed a little, it is worth putting this third line into php(as the current mainstream development language).ini. It should be noted that the prerequisite for turning it off is that you are not using the Zend encryption program.


2. Buffering

If we want to further improve the speed, we need to consider using buffering technology. There are some alternative solutions, including Zend Cache (beta version), APC, and Afterburner Cache, as well as jpCache, etc.

The above are buffer modules. They store the intermediate code generated by the first request for .php(as the current mainstream development language) file in the memory of the Web server. , and then return the "compiled" version for future requests. Because this reduces disk reads and writes, and all work in memory, this process can significantly improve application performance.

There are many such products readily available, so who should you choose?

Zend Cache is a good commercial product. After loading those large php (as the current mainstream development language) pages for the first time, you will obviously feel the speed. With the improvement, the server will set aside more resources. Unfortunately, this product costs money, but in some cases, you don't want to skimp on the money.

Afterburner Cache is a product of Bware Technologies. It is still in Beta version. It seems to be the same as Zend Cashe, but it cannot achieve as good results as Zend Cache, nor can it work with the Zend optimization engine, but it It's free, so I adopted this module.
