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！
