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"}
