我的生产计算机上有自定义错误处理程序：
register_shutdown_function( "check_for_fatal" );
set_error_handler('errHandle');
set_exception_handler( "log_exception" );
所有错误都将发送到邮件。但是格式很糟糕（直线文本）。
有没有人知道任何库、函数、拥有任何代码，这些代码会在 html 中格式化错误，并提供尽可能多的细节。（消息，文件，行，错误类，完整的调用堆栈，也许是全局变量 - $_GET，$_POST，...尽可能多的信息，所以我将更容易解决问题。

我也自己做。由于我处理了很多PDO，因此我还检查异常是否为PDO并添加一些详细信息。
输出并不漂亮，但它是为开发人员而不是其他人准备的。
