一个php的异常处理程序，功能很简单当发生重大错误时，写日志并友好提示用户.
代码：
<?php//exceptionHandle.php xiecongwen 20140620//define('DEBUG',true);/*** Display all errors when APPLICATION_ENV is development.*/if (defined('DEBUG')) {error_reporting(E_ALL);ini_set("display_errors", 1);}if(!defined('DEBUG')){/*** 当发生重大错误时 写日志 并友好提示用户* (PS:只所以将代码写在这里,是因为在其他地方注册时,出现问题无法调用配置函数.待完善...)*/function shutdownHandler(){/*** 写日志 此处直接写在根目录下shutdownlog.txt*/$lasterror = error_get_last();if($lasterror){$error = strval(date("Y-m-d h:i:s")).'=>'."[SHUTDOWN] lvl:" . $lasterror['type'] . " | msg:" . $lasterror['message'] . " | file:" . $lasterror['file'] . " | ln:" . $lasterror['line']."\n";file_put_contents('./log/'.date("Ymd").'shutdownlog.txt',$error,FILE_APPEND);//友好提示用户ob_end_clean();die('对不起,我出错了！');}}register_shutdown_function('shutdownHandler');}if(!defined('DEBUG')){ function errorHandler($errno, $errstr = '', $errfile = '', $errline = 0){//写日志$exception = new \ErrorException($errstr, 0, $errno, $errfile, $errline);$msg = strval(date("Y-m-d h:i:s")).'=>'.'Type:'.getErrTypeName($errno).'
