复制代码 代码如下:


function myErrorHandler($errno, $errstr, $errfile, $errline){
    if(!(error_reporting() &$errno)){return;}
    switch ($errno){
    case E_USER_ERROR:
        echo "My ERROR [$errno] $errstr
";
        echo "错误行:$errline 在文件:$errfile之中
";
        echo " PHP版本: " .PHP_VERSION ." (" .PHP_OS .")
";
        break;
    case E_USER_WARNING:
        echo "My WARNING [$errno] $errstr
";
        break;
    case E_USER_NOTICE:
        echo "My NOTICE [$errno] $errstr
";
        break;
    default:
        echo "Unknown error type: [$errno] $errstr
";
        break;
    }
    return true;
}

function trigger_test($age){//抛出错误的测试函数
    if($age 999) trigger_error("年龄不合法:$age岁", E_USER_ERROR);
    if($age     if($age > 40 && $age }
//如果只是简单统一地处理错误:
$errorHandler = set_error_handler("myErrorHandler");
trigger_test(1000);//会抛出一个error级的错误


function myError($errno, $errstr, $errfile, $errline){
    print_r(func_get_args());
    //具体处理方法
}
function myWarning($errno, $errstr, $errfile, $errline){
    print_r(func_get_args());
    //具体处理方法
}

function myNtice($errno, $errstr, $errfile, $errline){
    print_r(func_get_args());
    //具体处理方法
}

//如果要分别处理不同错误级别:
set_error_handler('myError',E_USER_ERROR);
set_exception_handler('myWarning',E_USER_WARNING);
set_exception_handler('myNtice',E_USER_NOTICE);
trigger_error('故意抛出个错误,还是很严重的哪一种!',E_USER_ERROR);
