PHP/Guzzle Target parent element - php

Question

I have an app using guzzle/php to make requests to a rest service.
When it yields a response, it includes nested arrays and objects:
[exampleBalances] => Array (
[0] => stdClass Object (
[balance] => 6
[name] => Prize One
[prizeCode] => 38
)
[1] => stdClass Object (
[balance] => 5
[name] => Prize Two
[prizeCode] => 20
)
[2] => stdClass Object (
[balance] => 4
[name] => Prize Four
[prizeCode] => 39
)
)
Until now Ive been pulling the value based on the order:
$prizeThree = $response->exampleBalances['3']->balance;
However, the service wont display any 'prizes' if the customer has 0, so the example above would no longer be accurate if a new item was added:
[exampleBalances] => Array (
[0] => stdClass Object (
[balance] => 6
[name] => Prize One
[prizeCode] => 38
)
[1] => stdClass Object (
[balance] => 5
[name] => Prize Two
[prizeCode] => 20
)
[2] => stdClass Object (
[balance] => 8
[name] => Prize Three
[prizeCode] => 54
)
[3] => stdClass Object (
[balance] => 4
[name] => Prize Four
[prizeCode] => 39
)
)
Is there a way to target the correct element, without using the order that it appears in the response?
I could not find any documentation, but its difficult to convey the issue. I was thinking there may be someway to create a condition to check an elements inner values (preferably the 'prize code') Any help would be greatly appreciated.

In PHP 5.5.0 or newer, you can use the array_column() function to do this search:
$index = array_search($prizeCodeSearch, array_column($exampleBalances, 'prizeCode'));
$element = $exampleBalances[$index];
