这有点令人困惑，因为这种事情通常是由SQL错误引起的，但是..or die(mysql_error());行应该已经解决了.检查循环的内容，确认您没有覆盖$result变量.

That's slightly confusing, since this sort of thing is usually caused by an SQL error, however the line ..or die(mysql_error()); should have picked that up. Check the contents of your loop that you're not overwriting the $result variable.
