Add xml child to array php - php

Question

I'm trying to add each <outfit>Subnodes</outfit> subnodes to an array using php.
My actual code:
public static function get_outfits($username) {
$files = self::user_files($username);
$data = self::request($files['outfits']);
$data = #simplexml_load_string($data);
if ( $data && count(#$data->xpath('//outfits/outfit')) > 0 ) {
foreach(#$data->xpath('//outfits/outfit/*') as $items) {
$response['outfits']['items'][] = array(
"url" => (string)$items['url'],
"c" => (string)$items['c'],
"c2" => (string)$items['c2'],
"displayName" => (string)$items['displayName'],
"z" => (string)$items['z'],
"id" => (string)$items['id'],
"isUgc" => (string)$items['isUgc']
);
}
}
return (isset($response) ? $response : false);
}
The xml document looks like the following: http://outfits.zwinky.com/users/220/287/_perverted/outfits.xml
Sadly the code is saving every existing child into one array. But I'm trying to create an array index for each <outfit></outfit> node which should contain the child elements.
For example:
Array[0] = Everything between the first <outfit><outfit>
Array[1] = Everything between the second <outfit><outfit>
Does anyone have an idea, how to create this?

Answer 1

You need two loops, one for the outfit elements and one for the inner item elements. On the other side, you don't need the condition, because iterating an empty array/node list works fine.
$outfits = new SimpleXmlElement($xml);
$result = [];
foreach ($outfits->xpath('outfit') as $outfit) {
$items = [];
foreach ($outfit->xpath('*') as $item) {
$items[$item->getName()] = [
"url" => (string)$item['url'],
"c" => (string)$item['c'],
"c2" => (string)$item['c2'],
"displayName" => (string)$item['displayName'],
"z" => (string)$item['z'],
"id" => (string)$item['id'],
"isUgc" => (string)$item['isUgc']
];
}
$result[] = [
'name' => (string)$outfit['name'],
'items' => $items
];
}
var_dump($result);
Output:
array(14) {
[0]=>
array(2) {
["name"]=>
string(6) "babe13"
["items"]=>
array(14) {
["head"]=>
array(7) {
["url"]=>
string(51) "http://.../assets/babe/heads/01/head1"
["c"]=>
string(8) "0xF4C4A4"
["c2"]=>
string(8) "0xffffff"
["displayName"]=>
string(0) ""
["z"]=>
string(5) "33000"
["id"]=>
string(0) ""
["isUgc"]=>
string(0) ""
}
["face"]=>
array(7) {
["url"]=>
string(50) "http://.../assets/babe/faces/01/grl1"
["c"]=>
string(3) "0x0"
["c2"]=>
string(8) "0xFF0000"
["displayName"]=>
string(5) "girl1"
["z"]=>
string(5) "34000"
["id"]=>
string(8) "20014794"
["isUgc"]=>
string(0) ""
}
...

Answer 2

If this is the output you want :-
Array
(
[0] => Array
(
[url] => http://assets.zwinky.com/assets/babe/heads/01/head1
[c] => 0xF4C4A4
[c2] => 0xffffff
[displayName] =>
[z] => 33000
[id] =>
[isUgc] =>
)
[1] => Array
(
[url] => http://assets.zwinky.com/assets/babe/faces/01/grl1
[c] => 0x0
[c2] => 0xFF0000
[displayName] => girl1
[z] => 34000
[id] => 20014794
[isUgc] =>
)
[2] => Array
(
[url] => http://assets.zwinky.com/assets/babe/midsections/01/ms1
[c] => 0xBCE4FE
[c2] =>
[displayName] =>
[z] => 9000
[id] =>
[isUgc] =>
)
... etc etc
Then all you need to do is change the code to this
public static function get_outfits($username) {
$files = self::user_files($username);
$data = self::request($files['outfits']);
$data = #simplexml_load_string($data);
if ( $data && count(#$data->xpath('//outfits/outfit')) > 0 ) {
foreach(#$data->xpath('//outfits/outfit/*') as $items) {
// $response['outfits']['items'][] = array(
$response[] = array(
"url" => (string)$items['url'],
"c" => (string)$items['c'],
"c2" => (string)$items['c2'],
"displayName" => (string)$items['displayName'],
"z" => (string)$items['z'],
"id" => (string)$items['id'],
"isUgc" => (string)$items['isUgc']
);
}
}
return (isset($response) ? $response : false);
}
