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
    }
?>

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
     * @param string $errfile
     * @param int    $errline
     * @return void
     */
    public static function addError($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;
    }

    // [...]
}

好吧，似乎可以用其他方式捕获致命错误:)

ob_start('fatal_error_handler');

function fatal_error_handler($buffer){
    $error = error_get_last();
    if($error['type'] == 1){
        // Type, message, file, line
        $newBuffer='<html><header><title>Fatal Error </title></header>
                      <style>
                    .error_content{
                        background: ghostwhite;
                        vertical-align: middle;
                        margin:0 auto;
                        padding: 10px;
                        width: 50%;
                     }
                     .error_content label{color: red;font-family: Georgia;font-size: 16pt;font-style: italic;}
                     .error_content ul li{ background: none repeat scroll 0 0 FloralWhite;
                                border: 1px solid AliceBlue;
                                display: block;
                                font-family: monospace;
                                padding: 2%;
                                text-align: left;
                      }
                      </style>
                      <body style="text-align: center;">
                        <div class="error_content">
                             <label >Fatal Error </label>
                             <ul>
                               <li><b>Line</b> ' . $error['line'] . '</li>
                               <li><b>Message</b> ' . $error['message'] . '</li>
                               <li><b>File</b> ' . $error['file'] . '</li>
                             </ul>

                             <a href="javascript:history.back()"> Back </a>
                        </div>
                      </body></html>';

        return $newBuffer;
    }
    return $buffer;
}

不是真的。之所以叫致命错误，是因为它们是致命的。你无法从中恢复过来。

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();
?>

你不能在一个已注册的shutdown函数中抛出一个异常:

<?php
    function shutdown() {
        if (($error = error_get_last())) {
           ob_clean();
           throw new Exception("fatal error");
        }
    }

    try {
        $x = null;
        $x->method()
    } catch(Exception $e) {
        # This won't work
    }
?>

但是您可以捕获请求并将其重定向到另一个页面。

<?php
    function shutdown() {
        if (($error = error_get_last())) {
           ob_clean();
           # Report the event, send email, etc.
           header("Location: http://localhost/error-capture");
           # From /error-capture. You can use another
           # redirect, to e.g. the home page
        }
    }
    register_shutdown_function('shutdown');

    $x = null;
    $x->method()
?>
