Simplexml elements extracts only first element but i need all elements - php

Question

i've this XML structure:
<response status="success">
<campaign>
<id>1</id>
<nameCampaign>Raccolta Punti CCN</nameCampaign>
<type>points</type>
<balances>
<balance>10.00 </balance>
</balances>
</campaign>
<campaign>
<id>6</id>
<nameCampaign>Abbonamenti</nameCampaign>
<type>subscription</type>
<balances>
<balance>6.00 Lampada solare</balance>
</balances>
<balances>
<balance>4.00 doccia solare</balance>
</balances>
<balances>
<balance>3.00 trifacciale</balance>
</balances>
</campaign>
</response>
And I need convert in array.
If i use
foreach($result->campaign as $bilancio) {
$balance[] = array ( 'nameCampaign' => (string)$bilancio->nameCampaign,
'balances' => (string)$bilancio->balances->balance );
} // foreach
I obtain this array
Array
(
[0] => Array
(
[nameCampaign] => Raccolta Punti CCN
[balances] => 10.00
)
[1] => Array
(
[nameCampaign] => Abbonamenti
[balances] => 6.00 Lampada solare
)
)
How could you note, id 6 has three sub-node (balances->balance) and not only one. How i could obtain a complete array?
Thank you to all and have a nice weekend!

Instead of reading (which will always give you the first element only with simeplxml), you iterate over all elements with foreach.
Here's a way:
$balance = array();
foreach ($result->campaign as $campaign)
{
$arr = array();
foreach ($campaign->balances as $campaignBalance)
{
$arr[] = (string) $campaignBalance->balance;
}
$balance[] = array(
'nameCampaign' => (string) $campaign->nameCampaign,
'balances' => $arr
);
}
print_r($balance);
Which will give you this result:
Array
(
[0] => Array
(
[nameCampaign] => Raccolta Punti CCN
[balances] => Array
(
[0] => 10.00
)
)
[1] => Array
(
[nameCampaign] => Abbonamenti
[balances] => Array
(
[0] => 6.00 Lampada solare
[1] => 4.00 doccia solare
[2] => 3.00 trifacciale
)
)
)
