如果使用PHP， >= 5.1.0 只需对errrexception类执行如下操作:

<?php
    // Define an error handler
    function exception_error_handler($errno, $errstr, $errfile, $errline ) {
        throw new ErrorException($errstr, $errno, 0, $errfile, $errline);
    }

    // Set your error handler
    set_error_handler("exception_error_handler");

    /* Trigger exception */
    try
    {
        // Try to do something like finding the end of the internet
    }
    catch(ErrorException $e)
    {
        // Anything you want to do with $e
    }
?>

我开发了一种方法来捕获PHP中的所有错误类型(几乎所有)!我不确定E_CORE_ERROR(我认为不会仅适用于该错误)!但是，对于其他致命错误(E_ERROR, E_PARSE, E_COMPILE…)，只使用一个错误处理函数就可以正常工作!这就是我的解决方案:

把下面的代码放在你的主文件(index.php)上:

<?php
    define('E_FATAL',  E_ERROR | E_USER_ERROR | E_PARSE | E_CORE_ERROR |
            E_COMPILE_ERROR | E_RECOVERABLE_ERROR);

    define('ENV', 'dev');

    // Custom error handling vars
    define('DISPLAY_ERRORS', TRUE);
    define('ERROR_REPORTING', E_ALL | E_STRICT);
    define('LOG_ERRORS', TRUE);

    register_shutdown_function('shut');

    set_error_handler('handler');

    // Function to catch no user error handler function errors...
    function shut(){

        $error = error_get_last();

        if($error && ($error['type'] & E_FATAL)){
            handler($error['type'], $error['message'], $error['file'], $error['line']);
        }

    }

    function handler( $errno, $errstr, $errfile, $errline ) {

        switch ($errno){

            case E_ERROR: // 1 //
                $typestr = 'E_ERROR'; break;
            case E_WARNING: // 2 //
                $typestr = 'E_WARNING'; break;
            case E_PARSE: // 4 //
                $typestr = 'E_PARSE'; break;
            case E_NOTICE: // 8 //
                $typestr = 'E_NOTICE'; break;
            case E_CORE_ERROR: // 16 //
                $typestr = 'E_CORE_ERROR'; break;
            case E_CORE_WARNING: // 32 //
                $typestr = 'E_CORE_WARNING'; break;
            case E_COMPILE_ERROR: // 64 //
                $typestr = 'E_COMPILE_ERROR'; break;
            case E_CORE_WARNING: // 128 //
                $typestr = 'E_COMPILE_WARNING'; break;
            case E_USER_ERROR: // 256 //
                $typestr = 'E_USER_ERROR'; break;
            case E_USER_WARNING: // 512 //
                $typestr = 'E_USER_WARNING'; break;
            case E_USER_NOTICE: // 1024 //
                $typestr = 'E_USER_NOTICE'; break;
            case E_STRICT: // 2048 //
                $typestr = 'E_STRICT'; break;
            case E_RECOVERABLE_ERROR: // 4096 //
                $typestr = 'E_RECOVERABLE_ERROR'; break;
            case E_DEPRECATED: // 8192 //
                $typestr = 'E_DEPRECATED'; break;
            case E_USER_DEPRECATED: // 16384 //
                $typestr = 'E_USER_DEPRECATED'; break;
        }

        $message =
            '<b>' . $typestr .
            ': </b>' . $errstr .
            ' in <b>' . $errfile .
            '</b> on line <b>' . $errline .
            '</b><br/>';

        if(($errno & E_FATAL) && ENV === 'production'){

            header('Location: 500.html');
            header('Status: 500 Internal Server Error');

        }

        if(!($errno & ERROR_REPORTING))
            return;

        if(DISPLAY_ERRORS)
            printf('%s', $message);

        //Logging error on php file error log...
        if(LOG_ERRORS)
            error_log(strip_tags($message), 0);
    }

    ob_start();

    @include 'content.php';

    ob_end_flush();
?>

我开发这个函数是为了使“沙盒”代码能够导致致命错误。由于从闭包register_shutdown_function抛出的异常不会从预致命错误调用堆栈中触发，因此我被迫在此函数之后退出，以提供统一的使用方法。

function superTryCatchFinallyAndExit( Closure $try, Closure $catch = NULL, Closure $finally )
{
    $finished = FALSE;
    register_shutdown_function( function() use ( &$finished, $catch, $finally ) {
        if( ! $finished ) {
            $finished = TRUE;
            print "EXPLODE!".PHP_EOL;
            if( $catch ) {
                superTryCatchFinallyAndExit( function() use ( $catch ) {
                    $catch( new Exception( "Fatal Error!!!" ) );
                }, NULL, $finally );                
            } else {
                $finally();                
            }
        }
    } );
    try {
        $try();
    } catch( Exception $e ) {
        if( $catch ) {
            try {
                $catch( $e );
            } catch( Exception $e ) {}
        }
    }
    $finished = TRUE;
    $finally();
    exit();
}

在某些情况下，即使是致命的错误也应该被捕获(你可能需要在优雅地退出之前做一些清理工作，而不是直接死亡..)。

我在我的CodeIgniter应用程序中实现了一个pre_system钩子，这样我就可以通过电子邮件得到我的致命错误，这帮助我找到没有报告的错误(或在修复后报告的错误，因为我已经知道了它们:))。

Sendemail检查错误是否已经报告，这样它就不会多次向您发送已知错误的垃圾邮件。

class PHPFatalError {

    public function setHandler() {
        register_shutdown_function('handleShutdown');
    }
}

function handleShutdown() {
    if (($error = error_get_last())) {
        ob_start();
        echo "<pre>";
        var_dump($error);
        echo "</pre>";
        $message = ob_get_clean();
        sendEmail($message);
        ob_start();
        echo '{"status":"error","message":"Internal application error!"}';
        ob_flush();
        exit();
    }
}

使用register_shutdown_function记录致命错误，这需要PHP 5.2+:

register_shutdown_function( "fatal_handler" );

function fatal_handler() {
    $errfile = "unknown file";
    $errstr  = "shutdown";
    $errno   = E_CORE_ERROR;
    $errline = 0;

    $error = error_get_last();

    if($error !== NULL) {
        $errno   = $error["type"];
        $errfile = $error["file"];
        $errline = $error["line"];
        $errstr  = $error["message"];

        error_mail(format_error( $errno, $errstr, $errfile, $errline));
    }
}

必须定义error_mail和format_error函数。例如:

function format_error( $errno, $errstr, $errfile, $errline ) {
    $trace = print_r( debug_backtrace( false ), true );

    $content = "
    <table>
        <thead><th>Item</th><th>Description</th></thead>
        <tbody>
            <tr>
                <th>Error</th>
                <td><pre>$errstr</pre></td>
            </tr>
            <tr>
                <th>Errno</th>
                <td><pre>$errno</pre></td>
            </tr>
            <tr>
                <th>File</th>
                <td>$errfile</td>
            </tr>
            <tr>
                <th>Line</th>
                <td>$errline</td>
            </tr>
            <tr>
                <th>Trace</th>
                <td><pre>$trace</pre></td>
            </tr>
        </tbody>
    </table>";
    return $content;
}

使用Swift Mailer编写error_mail函数。

在Zend Framework 2中找到了很好的解决方案:

/**
 * ErrorHandler that can be used to catch internal PHP errors
 * and convert to an ErrorException instance.
 */
abstract class ErrorHandler
{
    /**
     * Active stack
     *
     * @var array
     */
    protected static $stack = array();

    /**
     * Check if this error handler is active
     *
     * @return bool
     */
    public static function started()
    {
        return (bool) static::getNestedLevel();
    }

    /**
     * Get the current nested level
     *
     * @return int
     */
    public static function getNestedLevel()
    {
        return count(static::$stack);
    }

    /**
     * Starting the error handler
     *
     * @param int $errorLevel
     */
    public static function start($errorLevel = \E_WARNING)
    {
        if (!static::$stack) {
            set_error_handler(array(get_called_class(), 'addError'), $errorLevel);
        }

        static::$stack[] = null;
    }

    /**
     * Stopping the error handler
     *
     * @param  bool $throw Throw the ErrorException if any
     * @return null|ErrorException
     * @throws ErrorException If an error has been catched and $throw is true
     */
    public static function stop($throw = false)
    {
        $errorException = null;

        if (static::$stack) {
            $errorException = array_pop(static::$stack);

            if (!static::$stack) {
                restore_error_handler();
            }

            if ($errorException && $throw) {
                throw $errorException;
            }
        }

        return $errorException;
    }

    /**
     * Stop all active handler
     *
     * @return void
     */
    public static function clean()
    {
        if (static::$stack) {
            restore_error_handler();
        }

        static::$stack = array();
    }

    /**
     * Add an error to the stack
     *
     * @param int    $errno
     * @param string $errstr

     * @return void
     */
    public static function addError($errno, $errstr = '', $errfile = '', $errline = 0)
    {
        $stack = & static::$stack[count(static::$stack) - 1];
        $stack = new ErrorException($errstr, 0, $errno, $errfile, $errline, $stack);
    }
}

这个类允许您在需要时启动特定的ErrorHandler。然后你也可以停止处理程序。

使用这个类，例如:

ErrorHandler::start(E_WARNING);
$return = call_function_raises_E_WARNING();

if ($innerException = ErrorHandler::stop()) {
    throw new Exception('Special Exception Text', 0, $innerException);
}

// or
ErrorHandler::stop(true); // directly throws an Exception;

一个更好的解决方案是独白: 链接到完整的类代码:https://github.com/Seldaek/monolog/blob/master/src/Monolog/ErrorHandler.php

它还可以使用register_shutdown_function函数处理FATAL_ERRORS。根据这个类，FATAL_ERROR是以下数组之一(E_ERROR, E_PARSE, E_CORE_ERROR, E_COMPILE_ERROR, E_USER_ERROR)。

class ErrorHandler
{
    // [...]

    public function registerExceptionHandler($level = null, $callPrevious = true)
    {
        $prev = set_exception_handler(array($this, 'handleException'));
        $this->uncaughtExceptionLevel = $level;
        if ($callPrevious && $prev) {
            $this->previousExceptionHandler = $prev;
        }
    }

    public function registerErrorHandler(array $levelMap = array(), $callPrevious = true, $errorTypes = -1)
    {
        $prev = set_error_handler(array($this, 'handleError'), $errorTypes);
        $this->errorLevelMap = array_replace($this->defaultErrorLevelMap(), $levelMap);
        if ($callPrevious) {
            $this->previousErrorHandler = $prev ?: true;
        }
    }

    public function registerFatalHandler($level = null, $reservedMemorySize = 20)
    {
        register_shutdown_function(array($this, 'handleFatalError'));

        $this->reservedMemory = str_repeat(' ', 1024 * $reservedMemorySize);
        $this->fatalLevel = $level;
    }

    // [...]
}
