<?php
namespace Home\Controller;
use Think\Controller;
class LoginController extends Controller {
public function index(){
$this->display();
}
public function login(){
if(IS_POST){
$a = $_SESSION['verify_code'];
echo $a;
}else{

echo "page is not";
}
}
public function verify(){
$config = array(
'fontSize'=>16,
'useCurve'=>false,
'length'=>4,
'imageW'=>130,
'imageH'=>34,
'useNoise'=>false,
'bg'=>array(238,238,238),
'codeSet'=>'0123456789',
);
$Verify = new \Think\Verify($config);
$Verify->entry();
}
} 我想取session里边的验证始终取不出来我到底哪里错了
