Get specific JSON data without decoding multiple links - php

Question

I have a problem with fetching the correct data from a decoded JSON file. I don't know if my question is correct since I don't really know what I am doing for the moment.
So, this is what I don't want to do.
$ln = 'https://api.steamprices.net/v2/csgoprices/?id='.market_hash_name.'&key=XXX';
$link1 = file_get_contents($ln);
$myarray1 = json_decode($link1, true);
echo $myarray1['median_price'];
I am trying to get the price for every steam skin that's being loaded in my code. What this code does is that it loads this api link for every item I load. So if I have 50 items, this link will be loaded 50 times, which is not accepted by the API.
What I want to do, is that I want to load it once, and fetch the prices for every item from that exact link. That link would look like this:
https://api.steamprices.net/v2/csgoprices/?&key=XXX
So, lets say I load it once, and then when I want to apply market_hash_name to it, how do I do?
I assume it is something like this.
$priceJson = file_get_contents('https://api.steamprices.net/v2/csgoprices/?key=XXX');
$priceData = json_decode($priceJson, true);
echo $priceData[''.$market_hash_name.'']['price'];
But it doesn't seem to work. I am sorry for this messy explanation, I an unfamiliar with this.
Note that an example response for the api link looks like this:
{
"-r-H1Z1 Shirt": {
"price": 0.11,
"image": "https://steamcommunity-a.akamaihd.net/economy/image/iGm5OjgdO5r8OoJ7TJjS39tTyGCTzzQwmWl1QPRXu8oaf69-NOHLAbqw_23aLe8AcRQ8-3uyKA7_CGvsJYds9U65FMF7i6AbXTJ8PDm57EliZdK7KLPuuh3dxC3m4m0ihzss0MKE6NtIt4qs-JukOX73WgETXYze_pxEBA",

Another output
{

"have":2,
"max":9,
"rate":95,
"tr":0
}

Well, the json string you provide isn't valid but something like this may help you
<?php
$jsonData=file_get_contents("json.file"); // simply contains your json string as posted
$jsonArray=json_decode($jsonData,true);
$jsonObject=json_decode($jsonData);
$list_of_MHN=array("2016 Invitational Crate","ANGRYPUG Motorcycle Helmet");
print_r($jsonArray);
exit;
foreach($jsonArray as $hash_name=>$arr){
if(in_array($hash_name,$list_of_MHN)){
print_r($arr);
}
}
for($i=0;$i<count($list_of_MHN);$i++){
if(isset($jsonArray[$list_of_MHN[$i]])){
print_r($jsonArray[$list_of_MHN[$i]]);
}
}
for($i=0;$i<count($list_of_MHN);$i++){
if(isset($jsonObject->$list_of_MHN[$i])){
print_r($jsonObject->$list_of_MHN[$i]);
}
}
?>
