PHP parse assoc. array or XML - php

Question

How to acces this assoc array?
Array
(
[order-id] => Array
(
[0] => 1
[1] => 2
)
)
as a result of XML parsing
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE request SYSTEM "http://shits.com/wtf.dtd">
<request version="0.5">
<order-states-request>
<order-ids>
<order-id>1</order-id>
<order-id>2</order-id>
...
</order-ids>
</order-states-request>
</request>
$body = file_get_contents('php://input');
$xml = simplexml_load_string($body);
$src = $xml->{'order-states-request'}->{'order-ids'};
foreach ($src as $order) {
echo ' ID:'.$order->{'order-id'};
// dont work - echoes only ID:1, why?
}
// ok, lets try just another way...
$items = toArray($src); //googled function - see at the bottom
print_r($items);
// print result - see at the top assoc array
// and how to acces order ids in this (fck) assoc array???
//------------------------------------------
function toArray(SimpleXMLElement $xml) {
$array = (array)$xml;
foreach ( array_slice($array, 0) as $key => $value ) {
if ( $value instanceof SimpleXMLElement ) {
$array[$key] = empty($value) ? NULL : toArray($value);
}
}
return $array;
}
MANY THANKS FOR ANY HELP!

Answer 1

What you want is:
$body = file_get_contents('php://input');
$xml = simplexml_load_string($body);
$src = $xml->{'order-states-request'}->{'order-ids'}->{'order-id'};
foreach ($src as $id)
{
echo ' ID:', $id, "\n";
}
Live DEMO.
What happens with your code is that you're trying to loop:
$xml->{'order-states-request'}->{'order-ids'}
Which is not the array you want, order-id is, as you can see on your dump:
Array
(
[order-id] => Array
