函数：

/*@desc：xml转数组@param data xml字符串@return arr 解析出的数组*/function xmltoarray($data){$obj = simplexml_load_string($data, 'SimpleXMLElement', LIBXML_NOCDATA);$json = json_encode($obj);$arr = json_decode($json, true); return $arr;}测试：
a. 代码：

<?php$string = <<<XML<?xml version='1.0'?> <document><title>Forty What?</title><from>Joe</from><to>Jane</to><body>I know that's the answer -- but what's the question?</body></document>XML;$arr = xmltoarray($string);var_dump($arr);

b. 输出：

array(4) {["title"]=>string(11) "Forty What?"["from"]=>string(3) "Joe"["to"]=>string(4) "Jane"["body"]=>string(57) "I know that's the answer -- but what's the question?"}
