Need to extract data from POST request with JSON response - php

Question

I have a JSON response that I'm trying to gather data from. Most of the data is not needed but the way it is structured I'm having a tough time figuring out how to just get the data I need. The strings and values are paired kinda weird.
I need to be able to pull the data using PHP, and I need the info from the characteristic fields. Specifically, I need to pull the value for "qualificationTier".
What would I use to pull that string/value from this JSON response?

Answer 1

Check if this works.
<?php
$data = json_decode($your_json);
$qualificationTier = "qualificationTier";
// qualificationTier name is at position 13 in characteristic array
$QualificationTierName = $data->site->place->characteristic[13]->name;
$QualificationTierValue = "";
// Confirm indeed if the string name at position 13 in characteristics is indeed qualificationTier before retrieving the value at the same position
if(strcmp($qualificationTier, $QualificationTierName) == 0 ){
// qualificationTier value is at position 13 in characteristic array
$QualificationTierValue = $data->site->place->characteristic[13]->value;
echo "QualificationTier Name : " + $QualificationTierName;
echo "QualificationTier Value : " + $QualificationTierValue;
}
?>

Answer 2

A simple way would be to loop the array and get value when the name matches your field. You should first decode the json response so you will have an object to work with. Then just loop and set the variable when you have a match.
<?php
$response = json_decode($_POST['json-name']);
$qualificationTier = null;
foreach ($response->site->place->characteristic as $c) {
if ($c->name === 'qualificationTier') {
$qualificationTier = $c->value;
}
}
