如何处理解析错误和致命错误？

[英]How do I handle parse and fatal errors?

原文 2011-06-19 05:57:59 0 2 php/ error-handling/ fatal-error/ parse-error

I wrote a custom error handler for my site and I'm aware that PHP doesn't allow handling of parse and fatal errors. 我为我的站点编写了一个自定义错误处理程序，并且我知道PHP不允许处理解析错误和致命错误。 Is there something I can do to make it handle these errors? 我可以做些什么使它处理这些错误吗？ I don't want them being outputted to the user (but I want to use my error handler for them). 我不希望将它们输出给用户（但我想对它们使用错误处理程序）。

Thanks! 谢谢！

2 个解决方案

You could try register_shutdown_function . 您可以尝试register_shutdown_function 。 If there is an error (even parse one) in one of files you have included/required this function will still be called. 如果您包含/需要的一个文件中存在错误（甚至解析为一个错误），该函数仍将被调用。

Though you won't be able to use debug_backtrace because shutdown function will be called outside of your error, you could try to use error_get_last to get some information about the error. 尽管由于将在错误之外调用关闭函数，所以您将无法使用debug_backtrace ，但是您可以尝试使用error_get_last获取有关该错误的一些信息。

If it can't parse your script, it won't be able to parse your custom error handler. 如果无法解析脚本，则无法解析自定义错误处理程序。

You should have display_errors off in your php.ini and also set error_reporting to none when your site is in production. 您应该在php.ini关闭display_errors ，并在网站投入生产时将error_reporting设置为none。

Also, I believe set_error_handler() can handle fatal errors. 另外，我相信set_error_handler() 可以处理致命错误。
