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 // 自定义异常函数 set_exception_handler( 'handle_exception' ); // 自定义错误函数 set_error_handler( 'handle_error' ); /** * 异常处理 * * @param mixed $exception 异常对象 * @author HdhCmsTestphpfensi测试数据 */ function handle_exception( $exception ) { Error::exceptionError( $exception ); } /** * 错误处理 * * @param string $errNo 错误代码 * @param string $errStr 错误信息 * @param string $errFile 出错文件 * @param string $errLine 出错行 * @author HdhCmsTestphpfensi测试数据 */ function handle_error( $errNo , $errStr , $errFile , $errLine ) { if ( $errNo ) { Error::systemError( $errStr , false, true, false); } } /** * 系统错误处理 * * @author HdhCmsTestphpfensi测试数据 */ class Error { public static function systemError( $message , $show = true, $save = true, $halt = true) { list( $showTrace , $logTrace ) = self::debugBacktrace(); if ( $save ) { $messageSave = '<b>' . $message .
