将XML字符串装换成PHP对象

最近做一个CRM的接口，需要接受CRM发出的XML数据，再在PHP端做处理，现在把php解析xml的代码贴出：

 

 

empty($_GET['data']) ? $data = $_POST['data'] : $_GET['data'];

$xml_parser = xml_parser_create();

xml_parse_into_struct($xml_parser, $data, $vals, $index);
xml_parser_free($xml_parser);

$params = array();
$level = array();
foreach($vals as $xml_elem) {
    if ($xml_elem['type'] == 'open') {
        if (array_key_exists('attributes', $xml_elem)) {
            list($level[$xml_elem['level']], $extra) = array_values($xml_elem['attributes']);
        } else {
            $level[$xml_elem['level']] = $xml_elem['tag'];
        }
    }
    if ($xml_elem['type'] == 'complete') {
        $start_level = 1;
        $php_stmt = '$params';
        while ($start_level < $xml_elem['level']) {
            $php_stmt. = '[$level['.$start_level.']]';
            $start_level++;
        }
        $php_stmt. = '[$xml_elem[\'tag\']] = $xml_elem[\'value\'];';
        eval($php_stmt);
    }
}
echo "<pre>";
print_r($params);
echo "</pre>";

 

首先从request中获取传递过来的$_GET数据，然后调用php的xml解析函数，解析成字串，最后调用eval函数将字串转换成真正的PHP对象，结果是输出一个数组！
