Answer 1

此查询是否正确？因为如果不是并返回错误，那么下一行将无效。

$getUserInfo = mysql_query("SELECT * FROM `".DB_PREFIX."user_accounts` WHERE `ses_id`='".$_SESSION['ses_id']."'");

在查询后尝试回显mysql_error（）。

顺便说一下，你可能想看看mysqli。

Answer 2

而不是：

$user = mysql_query("SELECT * FROM `".DB_PREFIX."user_accounts` WHERE `fbid`='".$userInfo['id']."'");

DO

$sql = "SELECT * FROM `".DB_PREFIX."user_accounts` WHERE `fbid`='".$userInfo['id']."'";

$result = mysql_query($sql);
if (!$result) {
    $message  = '<b>Invalid query:</b><br>' . mysql_error() . '<br><br>';
    $message .= '<b>Whole query:</b><br>' . $sql . '<br><br>';
    die($message);
}

错误最有可能发生在呈现MySQL错误的SQL语句中，这将显示哪一个错误。

PHP错误。怎么解决？
