Php PDO&；Foreach（非法字符串偏移）

我已经修好了，不过谢谢你。我更改了票务查询和foreach
`
我可能会说，'SELECT*FROM ticket\u reply WHERE TID=：TID'，
此查询不会返回任何名为Content
的字段。请执行print\r（$TR）：退出并将结果传递到这里。很抱歉响应太晚，我得到了array（5）{[“ID”]=>string（1）“1”[“TID”]=>string（1）“1”[“Poster”]=>string（1）“1”[“Content”]=>string（23）”测试内容，kthx。”[“Date”=>string（10）“1444357123”}
但这只是一个元素吗？这是print\r（$TR）
还是print\r（$Reply）
这是print\r（$TR）
$Reply
返回字符串（1）“1”
这是问题所在，因为您试图从Reply$Reply['Content']获取内容
$Reply = $db->fetchRows('SELECT * FROM ticket_replies WHERE TID = :tid', [':tid' => $ID]);
foreach ($Reply as $TR) {
$Replier = $db->fetchRow(
'SELECT * FROM users WHERE UID = :poster',
[':poster' => $TR['Poster']]
);
