Comparison and feeling between APC and APCu in PHP5.4.36

Comparison and feeling between APC and APCu in PHP5.4.36

APC stands for Alternative PHP Cache. Optional php Cache, including opcache and user variable Cache.

APCu only contains the user variable cache.

Recently, the server php was upgraded from 5.2.17 to 5.4.36, and apache was upgraded from 2.2.22 to 2.4.10. memcache, apc, and zend optimization extensions were used in the previous Code. Therefore, I want to migrate the entire set to the new environment. After a period of experimentation, php ts 5.4 was used, mainly for ISAPI installation instead of FASTCGI. The reason is described below.

Need to download and install vc Runtime Library, version is VC9, http://www.microsoft.com/downloads/zh-cn/details.aspx? Displaylang = zh-cn & FamilyID = 9b2da534-3e03-4391-8a4d-074b9f2bc1bf

VC12 is vc2013, and VC11 is Vc2012.

Memcache logic is no problem, http://windows.php.net/downloads/pecl/releases/memcache/3.0.8/ this address to download the latest windows memcache, php5.3, php 5.4, php 5.5, php 5.6 have a corresponding package, 5.2 The package corresponding to the package has been canceled.

Apc encountered a new problem, the latest APC http://windows.php.net/downloads/pecl/releases/apc/3.1.13/ has canceled the 5.2 support, cut has not updated version for more than a year, it seems that the future of the php support for the high version will become a problem, therefore, we need to find new solutions.

Later found that many people in 5.4 use this http://windows.php.net/downloads/pecl/releases/apcu/4.0.7/, is said to be the official new recommendations, but confirmed only user caching, only support user cache, management tool apc. php has also changed. Configuration is much easier than APC configuration.

Again, zend optimization also removes 5.2 or more support. The latest zend guard only supports php of the ETS version and can only use the fastcgi mode, and supports php of Version 5.3 or above, the 5.2 support is also canceled. I want to use the ts version of php because zend guard seems to be purely intended to decode the new encryption code during the trial. Worker Process. Therefore, to solve the problem, we used the new recommended opcache extension, which is also officially supported by php5.3, php5.4, and php5.5. This is pure opcache. Address http://windows.php.net/downloads/pecl/releases/opcache/7.0.4/

Need to be configured in php. ini

[Opcache]
Zend_extension = d:/wamp/php/ext/php_opcache.dll
Opcache. enable = 1

APCu is automatically configured by default (via apc. php ):
