遇到以上报错提示.在研究了一番后发现,原来是最新的PHP7.0.9的memcached 扩展弃用了两个变量命名
以前老版本的
memcached.sess_lock_wait memcached.sess_lock_max_wait
被这个两个名字给取代了
memcached.sess_lock_wait_min memcached.sess_lock_wait_max
(注意“max”现在的变量名)。改变这些变量名和设置为0(默认)或其他值。这些默认值在配置的上方有说明。

所以说我们只需要将上面的那两个改为下面的这两个就可以了

首先找到 /usr/local/etc/php/7.0/conf.d 这个目录下的ext-memcached.ini
在15行改为 memcached.sess_lock_wait_min = 150000
然后在21行改为memcached.sess_lock_wait_max = 0;

然后保存退出,再运行 php -v 就不会报此错误了.
