SQL 查询未返回应返回的数据

Question

这是数据表，命名为"flagged_thread ">

tbody> <<tr>2

flagged_threadID	threadID	userID
1	2	1
	3	1
3	6	1

查看mysqli_fetch_assoc的文档:https://www.php.net/manual/de/function.mysql-fetch-assoc.php

你必须像这样在循环中使用这个函数:

$flagged_sql = "SELECT threadID FROM flagged_threads WHERE userID = 'current_userID'";
$flagged_qry = mysqli_query($dbconnect, $flagged_sql);
while($flagged_aa = mysqli_fetch_assoc($flagged_qry)) {
// do something with $flagged_aa
}
