windows中PHP 5.2.17 安装 eAccelerator方法
eAccelerator是一个开源php加速器，优化和动态内容缓存，提高了php脚本的缓存性能，使得PHP脚本在编译的状态下，对服务器的开销几乎完全消除,下面我来给各位同学介绍PHP 5.2.17 安装 eAccelerator方法
本包里有非线程安全与线程安全版本。eAccelerator_ts.dll 是线程安全版本，eAccelerator_nts.dll 是非线程安全版本。该eAccelerator使用最新发布的PHP 5.2.17编译，使用前请确认自己的PHP版本。文件内含Thread safe(线程安全)和Non Thread Safe(非线程安全版本)，请根据自己使用的PHP版本选择。
一、相关下载
eAccelerator 0.9.6.1 For PHP5.2.17（DLL）
二、安装方法
1、选择相应版本
根据您的PHP线程安全版本，选择相应文件，并复制到php目录下的子目录ext中，同时改名为php_eaccelerator.dll。
2、设置相应参数
[eaccelerator]
zend_extension_ts="d:/php5/ext/php_eaccelerator.dll"
eaccelerator.shm_size="64"
eaccelerator.cache_dir="d:/php5/tmp"
eaccelerator.enable="1"
eaccelerator.optimizer="1"
eaccelerator.check_mtime="1"
eaccelerator.debug="0"
eaccelerator.filter=""
eaccelerator.shm_max="0"
eaccelerator.shm_ttl="0"
eaccelerator.shm_prune_period="0"
eaccelerator.shm_only="0"
eaccelerator.compress="1"
eaccelerator.compress_level="9"
eaccelerator.keys = "shm"
eaccelerator.sessions = "shm"
eaccelerator.content = "shm"
请编辑C:windowsphp.ini文件（根据实际情况），复制以上参数到php.ini最底部，并修改以下路径。
zend_extension_ts="d:/php5/ext/php_eaccelerator.dll" #您的PHP路径
eaccelerator.cache_dir="d:/php5/tmp" #您的PHP临时文件路径（要有user可读写权限）
3、保存，重启IIS
在CMD中执行：IISRESET，重启IIS，并使用phpinfo查看，如果提示如下图，表示安装成功。
