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.
PHP系统异常处理类程序代码如下:
- <?php
-
-
- set_exception_handler('handle_exception');
-
-
- set_error_handler('handle_error');
-
-
-
-
-
-
-
- function handle_exception($exception) {
- Error::exceptionError($exception);
- }
-
-
-
-
-
-
-
-
-
-
- function handle_error($errNo, $errStr, $errFile, $errLine) {
- if ($errNo) {
- Error::systemError($errStr, false, true, false);
- }
- }
-
-
-
-
-
-
- class Error {
-
- public static function systemError($message, $show = true, $save = true, $halt = true) {
-
- list($showTrace, $logTrace) = self::debugBacktrace();
-
- if ($save) {
- $messageSave = '<b>' . $message . '</b><br /><b>PHP:</b>' . $logTrace;
- self::writeErrorLog($messageSave);
- }
-
- if ($show) {
- self::showError('system', "<li>$message</li>", $showTrace, 0);
- }
-
- if ($halt) {
- exit();
- } else {
- return $message;
- }
- }
-
-
-
-
-
-
-
- public static function debugBacktrace() {
- $skipFunc[] = 'Error->debugBacktrace';
-
- $show = $log = '';
- $debugBacktrace = debug_backtrace();
- ksort($debugBacktrace);
- foreach ($debugBacktrace as $k => $error) {
- if (!isset($error['file'])) {
-
- 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'] : '';

-
