Answer 1

你确定它实际上崩溃了apache并且不仅仅是你脚本中的错误吗？你在显示错误吗？

要显示错误，请将其放在页面顶部：

error_reporting(E_ALL);
ini_set('display_errors', '1');

如果这不起作用，我会继续拿走代码，直到它开始工作，然后慢慢构建它，直到它再次中断。然后，你会知道故障点。

Answer 2

你能告诉我们崩溃的意思吗？脚本没有完成执行吗？ Apache会返回500状态吗？

在一般的实践中，你应该简化/取出可能的代码区域，直到你可以让它中断，这样你就可以找到导致PHP自杀的语句。

例如，取出if块的内容......如果脚本有效，你知道你的问题就在那里。您还可以尝试一些策略性放置的die调用，这将停止执行并执行并在函数调用中打印参数的输出。例如，地点：

die(var_dump($details))

在你打电话$details = mysql_fetch_row($rst);之后

看看MySQL是不是在表现。
