Unset specific property of JSON in PHP

JSON

{
 "pages":{
   "index.php":{
      "status":"enabled",
      "theme":"dark",
      "identifier":"KMS"
  },
   "google.php":{
      "status":"enabled",
      "theme":"dark",
      "identifier":"KMS"
  },
   "doodle.php":{
      "status":"disabled",
      "theme":"light",
      "identifier":"transact"
   }
 }
}

In my PHP code I write 

$jsona = file_get_contents("../pages.json");
$jsonb = json_decode($jsona,true);  
$data = $jsonb['pages'];

Now if I want to delete the property "index.php" I write unset($data["index.php"] and then I write

file_put_contents("../pages.json",json_encode($data));

Though after going to my JSON file it deletes "pages"

actual outcome

{"google.php":{"status":"enabled","theme":"dark","identifier":"KMS"},"doodle.php":{"status":"disabled","theme":"light","identifier":"transact"}}

I need to just unset a specific child property of pages. Such as "google.php" or "doodle.php". I checked what is being posted as $data[$page] and it is the specific element. So why is it unsetting pages and leaving the rest of the properties?

Don't set $data to $jsonb['pages']. That's specifically setting your $data variable to a sub-section of your overall object.

Just use unset($jsonb['pages']['index.php']).
