centos7中php使用memcache

yum ?-y ?install ?memcached

memcached ?-u ?root ?-p ?11211 ?-m ?64m ?-d

yum ?-y ?install ?php-memcache ?#注意：有php-memcache和php-memcached两个扩展，这里php是作为客户端来调用memcached服务的，所以安装php-memcache

systemctl ?restart ?httpd

<?php$memcache = new Memcache;$memcache->connect(‘localhost‘, 11211) or die ("Could not connect");$arr = array(‘name‘=>‘lee‘,‘pass‘=>‘123456‘);$val = $memcache->get(‘key‘);if(!$val){ ?// 如果值在memcache中不存在，则设置他 ???$memcache->set(‘key‘,$arr);}var_dump($val);
