Thinkphp the implementation of a custom Redis processing session, Thinkphpredis

This paper describes the implementation of thinkphp custom Redis processing session. Share to everyone for your reference, as follows:

Everyday we will use to the session to save the user login information, commonly used to save the session: File saving (default), database storage, redis preservation, memcached and so on. Here is the main record of using thinkphp processing session with Redis to save the session usage.

1. Defined in the configuration item:

' Session_type ' = ' Redis ',//session save type ' session_prefix ' = ' sess_ ',//session prefix ' redis_host ' = ' 127.0.0.1 '// REDIS server address ' redis_port ' = 6379,//redis connection port number ' session_expire ' = 3600,//session expiration time

You can find the method that defines the session in the thinkphp/common/functions.php file, reading the session driver's judgment about 1179 rows or so. If we define the configuration item Session_type, a Redis object is new and the session store function Session_set_save_handler () is called.

2. Create a new Redis.class.php file in the Thinkphp\library\think\session\driver directory

The contents of the file are as follows:

<?phpnamespace think\session\driver;class Redis {//Redis Connection object private $redis;//Session Expiration time private $expire; /** * Open method * @param type $path * @param type $name * @return type */Public function open ($path, $name) {$thi S->expire = C (' Session_expire ')?  C (' Session_expire '): Ini_get (' session.gc_maxlifetime ');  $this->redis = new Redis ();  return $this->redis->connect (c (' Redis_host '), C (' Redis_port '));  }/** * Close * @return type */Public function close () {return $this->redis->close ();  }/** * Reads * @param string $id * @return Type */Public function read ($id) {$id = C (' Session_prefix '). $id;  $data = $this->redis->get ($id); Return $data?  $data: "; }/** * Write * @param string $id * @param type $data * @return Type * * Public function write ($id, $data) {$id = C (' Session_prefix ').  $id;  return $this->redis->set ($id, $data, $this->expire); }/** * destroys * @param string $id */Public functionDestroy ($id) {$id = C (' Session_prefix '). $id;  $this->redis->delete ($id);  }/** * Garbage collection * @param type $maxLifeTime * @return Boolean */Public Function GC ($MAXLIFETIME) {return true; }}

This completes the processing of the session by Redis.

Memcached is almost the same way as Redis!
