解析xml to array的php函数

整理了一下从网上搜到的一个类。网上大多数都是类，用起来忒麻烦，弄了个精简的。欢迎使用。//XML解析函数 @zairwolf
function xml2arr($xml){
$values = array();
$index  = array();
$array  = array();
$parser = xml_parser_create();
xml_parser_set_option($parser, XML_OPTION_SKIP_WHITE, 1);
xml_parser_set_option($parser, XML_OPTION_CASE_FOLDING, 0);
xml_parse_into_struct($parser, $xml, $values, $index);
xml_parser_free($parser);
$i = 0;
$name = $values[$i]['tag'];
$array[$name] = isset($values[$i]['attributes']) ? $values[$i]['attributes'] : '';
$array[$name] = _xml2arr($values, $i);
return $array;
}function _xml2arr($values, &$i){
$child = array();
if(isset($values[$i]['value'])) array_push($child, $values[$i]['value']);
while ($i++ < count($values)){
switch ($values[$i]['type']){
case 'cdata':
array_push($child, $values[$i]['value']);
break;
case 'complete':
$name = $values[$i]['tag'];
if(!empty($name)){
$child[$name]= !empty($values[$i]['value'])?($values[$i]['value']):'';
if(isset($values[$i]['attributes'])) $child[$name] = $values[$i]['attributes'];
}
break;
case 'open':
$name = $values[$i]['tag'];
$size = isset($child[$name]) ? sizeof($child[$name]) : 0;
$child[$name][$size] = _xml2arr($values, $i);
break;
case 'close':
return $child;
break;
}
}
return $child;
}

    好像有点bug
    $xml=<<<EOF
    <test>
        <head>this is head</head>
        <body>
            <items>
                <item id="1">item #1</item>
                <item id="2">item #2</item>
                <item id="3">item #3
                    <desc><![CDATA[<<<test>>>>]]></desc>
                </item>
            </items>
        </body>
    </test>
    EOF;print_R(xml2arr($xml));Array
    (
        [test] => Array
            (
                [head] => this is head
                [body] => Array
                    (
                        [0] => Array
                            (
