PHP XML和数组互相转换-白红宇

转换代码如下

//数组转XML    function arrayToXml($arr)    {        $xml = "
     
      ";        foreach ($arr as $key=>$val)        {            if (is_numeric($val)){                $xml.="<".$key.">".$val."
      ";            }else{                 $xml.="<".$key.">
      ";            }        }        $xml.="
     ";        return $xml;    }    //将XML转为array    function xmlToArray($xml)    {            //禁止引用外部xml实体        libxml_disable_entity_loader(true);        $values = json_decode(json_encode(simplexml_load_string($xml, 'SimpleXMLElement', LIBXML_NOCDATA)), true);                return $values;    }

Array转XML

$money = 101;$sender = "方倍工作室";$obj2 = array();$obj2['wxappid']             = APPID;$obj2['mch_id']             = MCHID;$obj2['mch_billno']            = MCHID.date('YmdHis').rand(1000, 9999);$obj2['client_ip']            = $_SERVER['REMOTE_ADDR'];$obj2['re_openid']             = $openid;$obj2['total_amount']       = $money;$obj2['min_value']             = $money;$obj2['max_value']             = $money;$obj2['total_num']             = 1;$obj2['nick_name']          = $sender;$obj2['send_name']          = $sender;$obj2['wishing']            = "恭喜发财";$obj2['act_name']              = "方倍工作室送红包";$obj2['remark']              = "关注公众账号";

转换后


       
      
        
      
       1235571234
        
      
       1235571234201605241726128109
        
      
        
      
        
      
       101
        
      
       101
        
      
       101
        
      
       1

XML转为Array

转换后

array(10) {  ["return_code"]=>  string(7) "SUCCESS"  ["return_msg"]=>  string(12) "发放成功"  ["result_code"]=>  string(7) "SUCCESS"  ["err_code"]=>  string(11) "MONEY_LIMIT"  ["err_code_des"]=>  string(12) "发放成功"  ["mch_billno"]=>  string(28) "1235571234201605241651123985"  ["mch_id"]=>  string(10) "1235571234"  ["wxappid"]=>  string(18) "wx1b7559b818e3c123"  ["re_openid"]=>  string(28) "oiPuduGV7gJ_MOSfAWpVmhhgXh-U"  ["total_amount"]=>  string(1) "1"}
