MYSQL选择具有3 WHERE子句

Question

我有这个代码

$set = 'mycrazyemail@gmail.com' 
$check_is_idk = $db->query("SELECT * FROM `ppl` WHERE `email` = '{$set}' AND `is` = 'idk' AND `belongs` = '{$id}'"); 

问题是什么麻烦？

你缺少在第一行的最后一个分号，它目前导致解析错误：

$set = 'mycrazyemail@gmail.com'; 
$check_is_idk = $db->query("SELECT * FROM `ppl` WHERE `email` = '{$set}' AND `is` = 'idk' AND `belongs` = '{$id}'");
