This makes almost all errors become catchable instance of ErrorException:
这使得几乎所有错误都成为可捕获的实例ErrorException：
set_error_handler(function($errno, $errstr, $errfile, $errline ){
throw new ErrorException($errstr, $errno, 0, $errfile, $errline);
});
use it before of the code that can give errors, for instances at the very top of your php file or in a common header included
在可能出错的代码之前使用它，例如在 php 文件的最顶部或包含的公共标头中
Limits: Severesterrors (PHP engine, server, syntax) cannot be handled with a user defined function: E_ERROR, E_PARSE, E_CORE_ERROR, E_CORE_WARNING, E_COMPILE_ERROR, E_COMPILE_WARNING, and most of E_STRICTraised in the file where set_error_handler() is called compromise it.
限制：病犬错误（PHP引擎，服务器，语法）不能与用户定义的函数来处理：E_ERROR，E_PARSE，E_CORE_ERROR，E_CORE_WARNING，E_COMPILE_ERROR，E_COMPILE_WARNING，大部分E_STRICT地方的set_error_han dler（）被调用妥协它在文件中提出的。
But, if syntax is correct and server don't broke, these errors should not appear.
但是，如果语法正确且服务器没有损坏，则不应出现这些错误。
If needed, you could workaround it with the register_shutdown_function()and error_get_last()
如果需要，您可以使用register_shutdown_function()和解决它error_get_last()

Try launch this web page, you should see "Message: Division by Zero".
尝试启动此网页，您应该会看到“消息：除以零”。
// Set Error Handler
set_error_handler (
function($errno, $errstr, $errfile, $errline) {
throw new ErrorException($errstr, $errno, 0, $errfile, $errline);
}
);
// Trigger an exception in a try block
try {
$a = 3/0;
echo $a;
}
catch(Exception $e) {
echo 'Message: ' .$e->getMessage();
}

I quite like the error handling from the kohana framework. You'd have to do a bit of work to pull it out though.
我非常喜欢 kohana 框架的错误处理。你必须做一些工作才能把它拉出来。
It will allow you to do error logging to a file and email a recipient. It also enables you to redirect to your friendly error page.
它将允许您将错误记录到文件并通过电子邮件发送给收件人。它还使您能够重定向到友好的错误页面。
