array(
array("name"=>"haha1",id=1,pid=0),
array("name"=>"haha2",id=2,pid=0),
array("name"=>"haha2,1",id=3,pid=2),
array("name"=>"haha2,2",id=4,pid=2),
array("name"=>"haha3",id=5,pid=0),
array("name"=>"haha3,1",id=6,pid=5),
array("name"=>"haha3.2",id=7,pid=5),
)
?>

把最上面的xml代码转换成下面php数组

下面是我写的代码，转换时候pid不对劲，我怎么调试都不行，还请指导
$xml = simplexml_load_file("hh.xml");
$arr = json_decode(json_encode($xml),TRUE);
print_r(arrto2($arr['hh']));
function arrto2($arr,$pid=0){
    static $i=1;
    static $data=array();
    foreach($arr as $v){
        if(is_array($v)){
            foreach($v as $z => $x){
                if($z==="@attributes"){
                    $v["@attributes"]['id']=$i;
                    $v["@attributes"]['pid']=$pid;
                $data[$i]=$v["@attributes"];

                }else{
                    arrto2($x,$i);
                }

                $i++;
            }
        }
    }
    return $data;
}

现在问题解决了，不错还有一个问题，解析中文时候会乱码，编码是gb2312,用utf8正常

回复讨论(解决方案)

问题解决了

arrto2($x,$v["@attributes"]['id']);就ok了

加上meta charset就不会乱码了。

hh.xml

<?xml version="1.0" encoding="gb2312"?><www><hh name="haha1哈哈" /><hh name="haha2哈哈"><hh name="haha2.1哈哈" /><hh name="haha2.2哈哈" /></hh><hh name="haha3哈哈"><hh name="haha3.1哈哈" /><hh name="haha3.2哈哈" /></hh></www>
