tp5 r3 一个简单的SQL语句调试实例
先看效果
核心代码
- public function index()
- {
- if (IS_AJAX && session("uid")==1){
- $sql=input("post.sql");
- $sql=base64_decode($sql);
- if ($sql){
- if (preg_match(‘/INSERT INTO|DELETE|UPDATE\s/i‘, $sql, $info)){
- $result=\think\Db::execute($sql);
- }
- else{
- $result=\think\Db::query($sql);
- }
- return dump($result);//json_encode($result)
- }else{
- return "错误的sql语句";
- }
- }
- //读取所有的表
- $tables=\think\Db::query(‘SHOW TABLES‘);
- $this->assign(‘tables‘,$tables);
- $database=\think\Config::get("database");
- $this->assign(‘tkey‘,"tables_in_".$database["database"]);
- return $this->fetch();
- }
