Looping in a complex array - php

Question

hope you are fine today.
I have an xml file online that I stored it into an array using file_get_contents(), simplexml_load_string() json_encode and json_decode; using the above methods gave an array like this:
[data] => Array

Now I want to loop through that array, as I want to re-convert it into my XML format, I am able to access the first level of the array and the orderitems -> item -> code where the client purchased one single item, but I am not able to loop inside deeper level where the client purchased more than one item (second array)
here is my code
foreach($array['data']['transaction'] as $transaction){
//echo $transaction['fields']['transactionid']."<br>";
//echo $transaction['orderitems']['item']['code']."<br>";
if(isset($transaction['orderitems']['item']['code'])){
echo $transaction['orderitems']['item']['code']."<br>";
} else {
foreach($transaction['orderitems']['item'] as $multi_item){
echo "<--- MULTI ---><br>";
//tried so many things and none has worked;
//like $multi_item['code'];
}
}
}
how to access the code of each item purchased by john doe?

Answer 1

You can access this data by filtering the array.
In PHP >= 5.5.0 you can make a search like this;
$key = array_search('John Doe', array_column($yourArray, 'cardholdersname'));
This method will return the array that matched given criteria.
