MYSQL選擇具有3 WHERE子句

Question

我有這個代碼

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

問題是什麼麻煩？

你缺少在第一行的最後一個分號，它目前導致解析錯誤：

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