About Yii's method to improve the performance optimization of concurrent numbers-PHP Tutorial-php.cn

This article mainly introduces the performance optimization method of Yii to improve the number of concurrency. It has a certain reference value. Now I share it with you. Friends in need can refer to it

Turn on YII's APC cache

Add under the config/main.php components component:
```
'apccache'=>array( 'class'=>'system.caching.CApcCache' ),
```
Copy after login
Download php_apc.dll, file Put it under php/ext, it may be more troublesome to search....
Add the php_apc extension in php.ini:
```
extension=php_apc.dll apc.rfc1867 = on capc.max_file_size = 100M upload_max_filesize = 100M post_max_size = 100M
```
Copy after login
Restart apache, use Function info(), check whether there is apc extension.

Usage:

Yii::app()->apccache->get(id); Yii::app()->apccache->set(id,value,time);

Copy after login

2. Use yiilite.php
Import yii.php into the entry file index.php , change to introduce yiilite.php

run();

Copy after login

Note:

Open apc cache and then introduce yiilite.php, because there are some classes in this file that are not currently used will also be loaded in.
If apc cache is not turned on, website performance will be reduced.
