/**
* 作用：将xml转为array
*/
function xmlToArray($xml) {
//将XML转为array
$array_data = json_decode(json_encode(simplexml_load_string($xml, 'SimpleXMLElement', LIBXML_NOCDATA)), true);
return $array_data;
}效果：
<xml> <appid>wxd930ea5d5a258f4f</appid> <mch_id>10000100</mch_id> <device_info>1000</device_info> <body>test</body> <nonce_str>ibuaiVcKdpRxkhJA</nonce_str> <sign>9A0A8659F005D6984697E2CA0A9CF3B7</sign> </xml>
转化成：
Array ( [appid] => wxd930ea5d5a258f4f [mch_id] => 10000100 [device_info] => 1000 [body] => test [nonce_str] => ibuaiVcKdpRxkhJA [sign] => 9A0A8659F005D6984697E2CA0A9CF3B7 )
