多维数组递归问题

[qq277049]

//为了实现内容中去除HTML A标签
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);
		}
	}

	$test=array(1,2,34,5,array("a"=>"<a href=''>而</a>",1,23,array("df"=>"<a href=''>测试下</a>"),array(23,32)),"b"=>"<a href=''>三</a>");
    	htmla($test);
    	var_dump($test);
//结果
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" //超过2维就没法转换了。。
    [3] => string(5) "Array"
  }
  ["b"] => string(3) "三"
}

foreach($string as $k=>$v)

//$string[$k]=preg_replace("/<\/?a.*?>/","",$v);

htmla($string[$k]);
}
else
{
$string[$k]=preg_replace("/<\/?a.*?>/","",$v);

纠结啊。。。各种测试还以为传V进去错误。这边少了个ELSE
