PHP将XML转成数组的函数实例

$xmlfile = file_get_contents($path);
$ob= simplexml_load_string($xmlfile);
$json = json_encode($ob);
$configData = json_decode($json, true);
?>

如果你使用 curl 获取的 xml data
$xml = simplexml_load_string($data);
$data['tk'] = json_decode(json_encode($xml),TRUE);
如果是直接获取 URL 数据的话
$xml = simplexml_load_file($data);
$data['tk'] = json_decode(json_encode($xml),TRUE);
先把 simplexml 对象转换成 json，再将 json 转换成数组。

// Xml 转 数组, 包括根键
function xml_to_array( $xml )
{
$reg = "/<(w+)[^>]*>([\x00-\xFF]*)<\/\1>/";
if(preg_match_all($reg, $xml, $matches))
{
$count = count($matches[0]);
for($i = 0; $i < $count; $i++)
{
$subxml= $matches[2][$i];
$key = $matches[1][$i];
if(preg_match( $reg, $subxml ))
{
$arr[$key] = xml_to_array( $subxml );
}else{
$arr[$key] = $subxml;
}
}
}
return $arr;
}
// Xml 转 数组, 不包括根键
function xmltoarray( $xml )
{
$arr = xml_to_array($xml);
$key = array_keys($arr);
return $arr[$key[0]];
}

function simplexml_obj2array($obj){
if ($obj instanceof SimpleXMLElement) {
$obj = (array)$obj;
}

if (is_array($obj)) {
$result = $keys = array();
foreach( $obj as $key=>$value)
{
isset($keys[$key]) ? ($keys[$key] += 1) : ($keys[$key] = 1);

if( $keys[$key] == 1 )
{
$result[$key] = simplexml_obj2array($value);
}
elseif( $keys[$key] == 2 )
{
$result[$key] = array($result[$key], simplexml_obj2array($value));
}
else if( $keys[$key] > 2 )
{
$result[$key][] = simplexml_obj2array($value);
}
}
return $result;
} else {
return $obj;
}
}
$xml=simplexml_load_file("D:/ www.111com.net /lib/books.xml");

$rss = simplexml_obj2array($xml);
