PHP中XML和数组互相转换的方法

转换代码如下

    //数组转XML

    function arrayToXml($arr)

    {

        $xml = "<xml>";

        foreach ($arr as $key=>$val)

        {

            if (is_numeric($val)){

                $xml.="<".$key.">".$val."</".$key.">";

            }else{

                 $xml.="<".$key."><![CDATA[".$val."]]></".$key.">";

            }

        }

        $xml.="</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

<xml>

  <wxappid><![CDATA[wx1b7559b818e3c123]]></wxappid>

  <mch_id>1235571234</mch_id>

  <mch_billno>1235571234201605241726128109</mch_billno>

  <client_ip><![CDATA[127.0.0.1]]></client_ip>

  <re_openid><![CDATA[oiPuduGV7gJ_MOSfAWpVmhhgXh-U]]></re_openid>

  <total_amount>101</total_amount>

  <min_value>101</min_value>

  <max_value>101</max_value>

  <total_num>1</total_num>

  <nick_name><![CDATA[方倍工作室]]></nick_name>

  <send_name><![CDATA[方倍工作室]]></send_name>

  <wishing><![CDATA[恭喜发财]]></wishing>

  <act_name><![CDATA[方倍工作室送红包]]></act_name>

  <remark><![CDATA[关注公众账号]]></remark>

</xml>

XML转为Array

<xml>

<return_code><![CDATA[SUCCESS]]></return_code>

<return_msg><![CDATA[发放成功]]></return_msg>

<result_code><![CDATA[SUCCESS]]></result_code>

<err_code><![CDATA[MONEY_LIMIT]]></err_code>

<err_code_des><![CDATA[发放成功]></err_code_des>

<mch_billno><![CDATA[1235571234201605241651123985]]></mch_billno>

<mch_id>1235571234</mch_id>

<wxappid><![CDATA[wx1b7559b818e3c123]]></wxappid>

<re_openid><![CDATA[oiPuduGV7gJ_MOSfAWpVmhhgXh-U]]></re_openid>

<total_amount>1</total_amount>

</xml>

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"

}
