redis instead of php files stores instances of session
Please understand the usage of the PHP session_set_save_handler function before viewing the instance
Define the 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();
}
}
The code for creating 1 session_set.php is as follows
include("SessionManager.php");
new SessionManager();
$_SESSION['user_name']="xxdcsnd@sina.com";
The code for creating an session_set.php is as follows
include("SessionManager.php");
new SessionManager();
echo $_SESSION['user_name'];
Test output xxdcsnd@sina.com
Note: php.ini session.save-hadler is set to user, otherwise session_set_save_handler will not take effect
