PHP 类的问题
调用源码

PHP code

<!--Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/-->$obj_car = new class_car;$num_carId = $obj_car->fn_carAdd($_POST);

类源码

PHP code

<!--Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/-->class class_car {    function fn_carAdd($arr_post) {        print_r($arr_post);    }}

这样可以正常输出数组

PHP code

<!--Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/-->Array(    [action_post] => carAdd    [str_postChk] =>     [str_carName] => 高尔夫    [num_carBrand] => 7    [num_carModel] => 615    [str_carEmiss] => 1.4T    [str_carTrans] => MT)

类源码

PHP code

<!--Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/-->class class_car {    function fn_carAdd($arr_post) {        print_r($arr_post["str_carName"]);    }}

这样输出乱码，求解，文件本身编码都没问题

------解决方案--------------------
header发送编码。
加在程序开始就行了。

header('Content-Type:text/html; charset=utf-8');
