PHP Search JSON File and get result

Question

Here is my JSON File that contains my items. I would like to search for the item name and return the id.

CODE:

 $jsonitem = file_get_contents("data.json");

 $objitems = json_decode($jsonitem);


 $findById = function($id) use ($objname) {
  foreach (json_decode($objname) as $friend) {
    if ($friend->id === $id) return $friend->name;
  }
  return;
};

echo $findById('6') ?: 'No record found.';

JSON FILE:

[
       {
          "id":1,
          "name":"Candy Wrapper",
          "value":500,
       },
       {
          "id":2,
          "name":"Torch",
          "value":2000,
       }
    ]

Your logic is correct, but you have a couple of errors in your code:

You are referencing $objname, which is not set
You are decoding the data twice
As @Mikey pointed out, your JSON is invalid because of trailing commas on the "values" lines.

Try:

$findById = function($id) use ($objitems) {
    foreach ($objitems as $friend) {
        if ($friend->id == $id) return $friend->name;
     }

    return false;
};

His JSON file is also invalid because of the trailing commas on the "value" lines.

@Mikey Good catch, I didn't notice that.

As for the trailing commas sorry for the confusion, I shortened my list as they are quite expansive with game variables and such. Thanks, this solved my problem!
