PHP MYSQL WHERE AND跟OR

Question

想請問一下該怎麼下where條件

WHERE `status` = '已完成' 
AND `type` = ''
AND `phone` LIKE '%{$user}%'
OR `phone2` LIKE '%{$user}%'
OR `address` LIKE '%{$user}%'
OR `name` LIKE '%{$user}%'
OR `email` LIKE '%{$user}%'
ORDER BY `buytime` DESC

條件是"status一定要是已完成 然後type一定要是空"
然後其他任一個有符合的都可以

我這樣子做會變成status不是已完成 type不是空的也會被搜索出來

Answer 1

WHERE `status` = '已完成' 
AND `type` = ''
and (
 `phone` LIKE '%{$user}%'
or`phone2` LIKE '%{$user}%'
OR `address` LIKE '%{$user}%'
OR `name` LIKE '%{$user}%'
OR `email` LIKE '%{$user}%'
)
ORDER BY `buytime` DESC
