php使用 memcache 来存储 session 方法总结
设置session用memcache来存储
方法I: 在 php.ini 中全局设置
session.save_handler = memcache
session.save_path = "tcp://127.0.0.1:11211"
方法II: 某个目录下的 .htaccess
php_value session.save_handler "memcache"
php_value session.save_path "tcp://127.0.0.1:11211"
方法III: 再或者在某个一个应用中
1 ini_set("session.save_handler", "memcache"); 2 ini_set("session.save_path", "tcp://127.0.0.1:11211");
使用多个 memcached server 时用逗号","隔开,并且和 Memcache::addServer() 文档中说明的一样,可以带额外的参数"persistent"、"weight"、"timeout"、"retry_interval" 等等,类似这样的:"tcp://host1:port1?persistent=1&weight=2,tcp://host2:port2" 。
如果安装的PECL是memcached(依赖libmemcached库的那个扩展),则配置应为
Php代码 收藏代码
ini_set("session.save_handler", "memcached"); // 是memcached不是memcache
ini_set("session.save_path", "127.0.0.1:11211"); // 不要tcp:[/b]

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
