将数组转换成xml
调用语法：
$xml =\backend\models\core\Array2XML::createXML('root_node_name',$PHP_array);
echo $xml->saveXML();
例子：
$xmlArray = array(
"@attributes" =>[
"xmlns:xsi"=>"http://www.w3.org/2001/XMLSchema",],"order" => [
'volweight'=>1,'untread'=>'Abandoned','clcttype'=>[
"@attributes" =>[
"xmlns:xsi"=>"http://www.w3.org/2001/XMLSchema",'name'=>1,'receiver'=>[
'street' => 'guangzhou shenzhen nanfdmen','sender'=>[
'name'=>'Boxing Chen','postcode'=>'518000','country'=>'CN','province'=>440000,'city'=>'440304','company'=>'grandxing Tech','street'=>'8I 6building weipeng zhengzhong rd futian',]
);
$xml = \backend\models\core\Array2XML::createXML('orders',$xmlArray);
echo $xml->saveXML();
exit;
输出结果为：
<?xml version="1.0" encoding="UTF-8"?>
<orders xmlns:xsi="http://www.w3.org/2001/XMLSchema">
<order>
<volweight>1</volweight>
<untread>Abandoned</untread>
<clcttype xmlns:xsi="http://www.w3.org/2001/XMLSchema">
<name>1</name>
</clcttype>
<receiver>
<street>guangzhou shenzhen nanfdmen</street>
</receiver>
<sender>
<name>Boxing Chen</name>
<postcode>518000</postcode>
<country>CN</country>
<province>440000</province>
<city>440304</city>
<company>grandxing Tech</company>
<street>8I 6building weipeng zhengzhong rd futian</street>
</sender>
</order>
