php - localhost 当前无法处理此请求。运行特定代码时出现 HTTP ERROR 500

Question

更新:我发现 $event_start_date = strtotime($row['event_start_date'])); 和 $event_end_date = strtotime($row['event_end_date'])) ; 给出了错误。

我目前正在为我的任务创建一个事件管理网站。我收到此 localhost 当前无法处理此请求。每当使用这段代码时，都会出现 HTTP ERROR 500 。当我删除它时，它运行得很好。但奇怪的是，当我在 Mozila 中运行它时，它只显示一个白色的空白页面，而在 chrome 中运行它时，它会给我这个错误。顺便说一句，我使用 Uniserver 作为本地主机。

Answer 1

 $event_start_date = strtotime($row['event_start_date']));
 $event_end_date = strtotime($row['event_end_date']));

i think you have give here two brackets

$event_start_date = strtotime($row['event_start_date']);
$event_end_date = strtotime($row['event_end_date']);
