PHP系统异常处理类程序

以前我们用过的异常处理函数都是单个的，下面我找到一个非常的不错的异常处理类系统，不但可以控制错误还能给出好的界面哦。

' . $message . '
PHP:' . $logTrace;
            self::writeErrorLog($messageSave);
        }
        if ($show) {
            self::showError('system', "

$message

", $showTrace, 0); } if ($halt) { exit(); } else { return $message; } } /** * 代码执行过程回溯信息 * * @static * @access public */ public static function debugBacktrace() { $skipFunc[] = 'Error->debugBacktrace'; $show = $log = ''; $debugBacktrace = debug_backtrace(); ksort($debugBacktrace); foreach ($debugBacktrace as $k => $error) { if (!isset($error['file'])) { // 利用反射API来获取方法/函数所在的文件和行数 try { if (isset($error['class'])) { $reflection = new ReflectionMethod($error['class'], $error['function']); } else { $reflection = new ReflectionFunction($error['function']); } $error['file'] = $reflection->getFileName(); $error['line'] = $reflection->getStartLine(); } catch(Exception $e) { continue; } } $file = str_replace(SITE_PATH, '', $error['file']); $func = isset($error['class']) ? $error['class'] : ''; $func.= isset($error['type']) ? $error['type'] : ''; $func.= isset($error['function']) ? $error['function'] : ''; if (in_array($func, $skipFunc)) { break; } $error['line'] = sprintf('%04d', $error['line']); $show.= '
