tp5 r3 一个简单的SQL语句调试实例
先看效果

核心代码

1.     public function index()
2.     {
3.         if (IS_AJAX && session("uid")==1){
4.             $sql=input("post.sql");
5.             $sql=base64_decode($sql);
6.             if ($sql){
7.                 if (preg_match(‘/INSERT INTO|DELETE|UPDATE\s/i‘, $sql, $info)){
8.                     $result=\think\Db::execute($sql);
9.                 }
10.                 else{                    
11.                     $result=\think\Db::query($sql);
12.                 }
13.                 return dump($result);//json_encode($result)
14.             }else{
15.                 return  "错误的sql语句"; 
16.             }
17.             
18.         }
19.         //读取所有的表
20.         $tables=\think\Db::query(‘SHOW TABLES‘);
21.         $this->assign(‘tables‘,$tables);
22.         $database=\think\Config::get("database");
23.         $this->assign(‘tkey‘,"tables_in_".$database["database"]);
24.         return $this->fetch();
25.          
26.     }
