我正在尝试从sql数据库中回显多行，但是我收到错误警告。非法字符串偏移'日期'在....

$channel_check = mysql_query("SELECT content, Date FROM wgo WHERE Posted_By='$user' ORDER by `id` DESC;");

Answer 1

DATE是SQL中的数据类型，您需要使用反向标记

来转义它

SELECT content, `Date` FROM wgo WHERE Posted_By='$user' ORDER by `id` DESC

此外，您正在错误地访问您的行。行通常由单维数组表示，因此$ row ['content']和$ row ['Date']

Answer 2

$row是包含2个字段的1维数组：内容和日期。

尝试，

while ($row = mysql_fetch_array($channel_check)) {
    print_r($row);
    //$channel_name = $row['content']['Date'];
