A small example of php recursive call

/**
* Remove special characters and labels from array elements
*/
function delarraystr($array){
    if(is_array($array)){
        foreach ($array as $k=>$v){
            $array[$k] = delarraystr($array[$k]);
        }
    }else{
        $array = strip_tags($array);
        $array = preg_replace('/$/', '', $array);//价格梯度1000up
    }
    return $array;
}
?>
