php中，使用memcache作为session的save handler 一般会使用如下设置：
php.ini里：
session.save_handler = memcache
session.save_path = “localhost:11211″
项目配置里：
ini_set(“session.save_handler”, “memcache”);
ini_set(“session.save_path”, “127.0.0.1:11211″);
在网上很多资料会写成这样：
session.save_path = “tcp://localhost:11211″
就是连接前缀里添加了tcp:// 这是会导致php的memcache模块写入失败，切记一定不要添加tcp协议前缀！
session.save_path string
Defines a comma separated of hostname:port entries to use for session server pool, for example “sess1:11211, sess2:11211″.
If
you want to use ‘memcacheD’ extention not ‘memcache’ (there are two
diffrent extentions) for session control, you should pay attention to
modify php.ini
Most web resource from google is based on memcache because It’s earlier version than memcacheD. They will say as following
session.save_handler = memcache
session.save_path = “tcp://localhost:11211″
But it’s not valid when it comes to memcacheD
you should modify php.ini like that
session.save_handler = memcached
session.save_path = “localhost:11211″
Look, there is no protocol indentifier
