Thinkphp设置session共享使用 redis实现

'SESSION_OPTIONS'=>array(
"session.save_handler"=>"redis",
"session.save_path"=>"tcp://localhost:6379"//redis主服务器
),

public function session_test(){
session_start();
header("Content-type:text/html;charset=utf-8");
if(isset($_SESSION['test'])){
$_SESSION['test'] = $_SESSION['test'] + 1;
}else{
$_SESSION['test'] = 1;
}

print_r($_SESSION);
print_r(session_id());

}

public function session_test2(){
ini_set("session.save_handler", "redis");
ini_set("session.save_path", "tcp://localhost:6380");//redis从服务器
session_start();

print_r($_SESSION);
print_r(session_id());

}
