多維陣列遞迴問題

PHP code

//為了實現內容中去除HTML A標籤function htmla(&$string)    {        if(is_array($string))        {            foreach($string as $k=>$v)            {                $string[$k]=preg_replace("/<\/?a.*?>/","",$v);                if(is_array($v))                {                    htmla($string[$k]);                }            }        }else{            $string=preg_replace("/<\/?a.*?>/","",$string);        }    }    $test=array(1,2,34,5,array("a"=>"而",1,23,array("df"=>"測試下"),array(23,32)),"b"=>"三");        htmla($test);        var_dump($test);//結果array(6) {  [0] => string(1) "1"  [1] => string(1) "2"  [2] => string(2) "34"  [3] => string(1) "5"  [4] => array(5) {    ["a"] => string(3) "而"    [0] => string(1) "1"    [1] => string(2) "23"    [2] => string(5) "Array" //超過2維就沒法轉換了。。    [3] => string(5) "Array"  }  ["b"] => string(3) "三"}

------解決方案--------------------
foreach($string as $k=>$v)
{
//$string[$k]=preg_replace("/<\/?a.*?>/","",$v);
if(is_array($v))
{
htmla($string[$k]);
}
else
{
$string[$k]=preg_replace("/<\/?a.*?>/","",$v);
}
}
