Access values in nested foreach PHP - php

Question

I have a JSON file. (Steam API). I want to display player inventory in my website. I use this url: https://steamcommunity.com/id/majidsajadi/inventory/json/730/2
Then I decode it with json_decode function.
Now there are two arrays: rgInventory and rgDescription. I need to check if class id in rgInventory and classid in rgDescription match I use some of values in igDescription.
So I think I should use 2 foreach loop and a if condition to check if class id match. then I echo out the information I need.
The question is how should I use nested foreach?

Answer 1

You can use two nested foreach loops like this:
Assuming that $decoded_data is your decoded data after applying json_decode() function on the end result, like this: $decoded_data = json_decode($your_json_data, true);
foreach($decoded_data['rgInventory'] as $arr1){
foreach($decoded_data['rgDescriptions'] as $arr2){
if($arr1['classid'] == $arr2['classid']){
// both the classid matches
// your code
}
}
}

Answer 2

Try this code:
$steamData = json_decode(file_get_contents("https://steamcommunity.com/id/majidsajadi/inventory/json/730/2"), true);
if($steamData["success"] != 1){
exit();
}
$match = array();
foreach($steamData["rgInventory"] as $v1){
$match[$v1["classid"]]["match"] = false;
$match[$v1["classid"]]["count"] = 0;
}
foreach($steamData["rgDescriptions"] as $v2){
if(array_key_exists($v2["classid"],$match)){
$match[$v2["classid"]]["match"] = true;
$match[$v2["classid"]]["count"]++;
}
}
print_r($match);
