php中将SimpleXMLElement Object数组转化为普通数组
php中将SimpleXMLElement Object数组转化为普通数组
在PHP中可以用simplexml_load_file或者simplexml_load_string 方便地进行XML的分析，但是这两个方法返回的都是 SimpleXMLElement 用起来还是很不方便。
在支付宝接口demo里有这样的写法：
/** * 通过节点路径返回字符串的某个节点值 * $res_data——XML 格式字符串 * 返回节点参数 */function getDataForXML($res_data,$node){$xml = simplexml_load_string($res_data);$result = $xml->xpath($node);while(list( , $node) = each($result)) {return $node;}}总是觉得不怎么灵活，如果我想去所有的节点数据感觉操作一点都不方便。
其实php提供了更简单的方法，直接把 $xml 对象转换为数据就可以了
$xml = (array)$xml;
看代码 哈哈：
$_POST['notify_data'] = '<notify><payment_type>1</payment_type><subject>50个xx</subject><trade_no>xxx</trade_no><buyer_email>stefan321@qq.com</buyer_email><gmt_create>2012-02-27 15:26:28</gmt_create><notify_type>trade_status_sync</notify_type><quantity>1</quantity><out_trade_no>xxxx</out_trade_no><notify_time>2012-02-27 15:27:15</notify_time><seller_id>xxxx</seller_id><trade_status>TRADE_FINISHED</trade_status><is_total_fee_adjust>N</is_total_fee_adjust><total_fee>0.01</total_fee><gmt_payment>2012-02-27 15:27:15</gmt_payment><seller_email>xxxxx@gmail.com</seller_email><gmt_close>2012-02-27 15:27:14</gmt_close><price>0.01</price><buyer_id>xxxxx</buyer_id><notify_id>xxxxx</notify_id><use_coupon>N</use_coupon></notify>';$xml = simplexml_load_string($_POST['notify_data']);$notify['payment_type'] = $xml->xpath('/notify/payment_type');$notify['subject'] = $xml->xpath('/notify/subject');$notify['trade_no'] = $xml->xpath('/notify/trade_no');$notify['buyer_email'] = $xml->xpath('/notify/buyer_email');$notify['gmt_create'] = $xml->xpath('/notify/gmt_create');$notify['notify_type'] = $xml->xpath('/notify/notify_type');$notify['out_trade_no'] = $xml->xpath('/notify/out_trade_no');$notify['notify_time'] = $xml->xpath('/notify/notify_time');$notify['seller_id'] = $xml->xpath('/notify/seller_id');$notify['trade_status'] = $xml->xpath('/notify/trade_status');$notify['total_fee'] = $xml->xpath('/notify/total_fee');$notify['seller_email'] = $xml->xpath('/notify/seller_email');$notify['price'] = $xml->xpath('/notify/price');$notify['buyer_id'] = $xml->xpath('/notify/buyer_id');$notify['notify_id'] = $xml->xpath('/notify/notify_id');print_r($notify);$xml = (array)$xml;print_r($xml);输出：
