How to pull out a specific parameter value?

Question

PHP

There is a block, I will give a part:

$close_ah[$json['d']['data']['back'][$key]['mixedParameterName']][$b_key]['1']['close'] = $b_value[0];
                          
$outcome_ah[$json['d']['data']['back'][$key]['mixedParameterName']] = $json['d']['data']['back'][$key]['OutcomeID'];

As a result, all values ​​of the 'mixedParameterName' parameter and data on them are collected for the database, but I need to select a specific value of one - '2:2' , and not all in a row, how to achieve this? Googled, made attempts - did not find how, I just "zero" in the code, it is not possible to ask the person who wrote it, there is no connection with him.
