redis replaces the instance of PHP file storage session
Please understand the usage of PHP session_set_save_handler function before viewing the example
Define a SessionManager class
class SessionManager { private $redis; public function __construct(){ $this->redis = new Redis(); $this->redis->connect('192.168.0.102', 6379); $retval =session_set_save_handler( array($this,"open"), array($this,"close"), array($this,"read"), array($this,"write"), array($this,"destroy"), array($this,"gc") ); session_start(); } public function open($path,$name){ return true; } public function close(){ return true; } public function read($id){ $session_value = $this->redis->get($id); if($session_value){ return $session_value; }else{ return ""; } } public function write($id,$data){ if($this->redis->set($id,$data)){ return true; }else{ return false; } } public function destroy($id){ if($this->redis->delete($id)){ return true; }else{ return false; } } public function gc($maxlifetime){ return true; } public function __destruct(){ session_write_close(); } }
Create a session_set.php and the code is as follows
include("SessionManager.php"); new SessionManager(); $_SESSION['user_name']="xxdcsnd@sina.com";
Create a session_set.php and the code is as follows
include("SessionManager.php"); new SessionManager(); echo $_SESSION['user_name'];
Test output result xxdcsnd@sina.com
Note: php.ini session.save- hadler is set to user, otherwise session_set_save_handler will not take effect
