关于php_memcache.dll 扩展安装的有关问题。 新手求指点

关于php_memcache.dll 扩展安装的问题。。 新手求指点
我用的是win7操作系统。。

php的版本是 5.2.17

然后下载了php_memcache-2.2.6-5.3-nts-vc9-x86 放在php扩展文件夹里，然后在 php.ini 中打开扩展，重启appache，但是在phpinfo()函数中没有这个库。

然后又下载了 php_memcache-2.2.6-5.3-vc9-x86 问题和上面的一样。


谁能告诉我怎么回事？

[解决办法]
只需把其中的.dll文件拷贝至ext目录下。

打开php.ini（确保是php加载的按个ini文件）添加一行

extension=php_memcache.dll 去前面分号是必须的。

重启apache

把php升级到5.3 以后版本再看吧.
另外确认你修改的php.ini 是phpinfo 內同路径的文件

探讨

恩 就是这么做的，可是不行引用:

应该有。谷歌搜去吧。
