wampserver配置memcache，wampservermemcache

我用的环境是win7 64位的操作系统，wampserver也是64位，版本是2.5的，其中带的php版本是5.5的。

配置memcache的步骤：

第一步，先下载memcahed.exe和php_memcache.dll扩展。下载地址：http://pan.baidu.com/s/1jG8OREu

第二步，安装memcache和配置memcache扩展。把memcache.exe的压缩包解压到wampserver的bin目录下，和php的目录同级。

然后在dos中执行如图中的命令；注：下图中的路径换成你的memcached.exe所在的路径。

接下来配置php的mecahce扩展，将php_memcache.dll放到php的ext目录下，我的目录是D:\wamp\bin\php\php5.5.12\ext；

然后在php.ini中添加一行extension=php_memcache.dll，注意前面不要加分号。然后重启wampserver的服务。

注：因为在配置memcache的时候重启wampserver不报什么错误，我在phpinfo里面也没有检测到memcache。所以只能直接上代码进行测试，索性我运气不错，配置成功了。

下面是我进行测试的代码：

在此再附上部分php操作memcache常用的函数：

Memcache::add 添加一个值，如果已经存在，则返回false

Memcache::addServer 添加一个可供使用的服务器地址

Memcache::close 关闭一个Memcache对象

Memcache::connect 创建一个Memcache对象

memcache_debug 控制调试功能

Memcache::decrement 对保存的某个key中的值进行减法操作

Memcache::delete 删除一个key值

Memcache::flush 清除所有缓存的数据
