steam json url of inventory def_index

[samcadek]

https://steamcommunity.com/profiles/76561198182213262/inventory/json/440/2 this is the file and I would like to get the def_index from rgDescriptions in descriptions in app_data

foreach ($inventories['rgDescriptions'] as $key => $description) {       
  if (isset($description['descriptions'])) {
    foreach ($description['descriptions'] as $key => $effects2) {
      if (isset($effects2['app_data'])) {
        $effectsValue2 = $effects2['app_data'];
        foreach ($effectsValue2 as $key => $treba) {
          if (isset($effectsValue2['def_index'])) {
              $effectsValue3 = $effectsValue2['def_index'];
          }
        }
      }
    }
  }
}

I made this but the respond is rly random

There are a few concepts that will help you.

The first is the use of the empty function.  For arrays it is especially useful, in that it checks both for existence and whether or not the item actually has a value.  While you can foreach() an empty array, with empty your code can already detect that the array is empty and the foreach will never be entered.

This revised code should help you better understand the variations in the data:

 

if (!empty($inventories['rgDescriptions'])) {
    foreach ($inventories['rgDescriptions'] as $key => $description) {       
        if (!empty($description['descriptions'])) {
            foreach ($description['descriptions'] as $key => $effects2) {
                var_dump($effects2);
                
            }
        }
    }
}

 

This reveals that app_data is an array that exists in some entries, and when it does, appears to have key/value pairs.    

array(3) {
  ["value"]=>
  string(15) "    Death Stare"
  ["color"]=>
  string(6) "4b69ff"
  ["app_data"]=>
  array(1) {
    ["def_index"]=>
    string(5) "31225"
  }
}
array(3) {
  ["value"]=>
  string(24) "    Spooky Head-Bouncers"
  ["color"]=>
  string(6) "4b69ff"
  ["app_data"]=>
  array(1) {
    ["def_index"]=>
    string(5) "31209"
  }
}

 

A useful function for finding out if an array has a particular key is array_key_exists. This helps you determine if the app_data array contains a 'def_index' value or not.  There are many entries in your data that don't have one.

Putting this all together, I added code to output the item 'value' which appears to be a name, and the def_index value you wanted.  I don't have any idea what that value actually is, so I included the name to make this demonstration somewhat interesting.  Frequently the name has whitespace in it, so I used trim() to remove that.

if (!empty($inventories['rgDescriptions'])) {
    foreach ($inventories['rgDescriptions'] as $key => $description) {       
        if (!empty($description['descriptions'])) {
            foreach ($description['descriptions'] as $key => $effects2) {
                // var_dump($effects2);
                if (!empty($effects2['value']) && !empty($effects2['app_data'])) {
                    if (array_key_exists('def_index', $effects2['app_data'])) {
                        echo trim($effects2['value']) . ": {$effects2['app_data']['def_index']}" . PHP_EOL; 
                    }
                } 
            }
        }
    }
}
