Remove item from JSON returned from API

I’m new to PHP and have some trouble trying to delete an item from some data returned by an API

function getData()
{    
    $ch = curl_init($url);
    curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "GET");
    curl_setopt($ch, CURLOPT_POSTFIELDS, "");
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json',));
    

    $data = curl_exec($ch);


    echo $data;
    exit();
}

Here is the JSON data, I want to remove the item with Id 11, how can I do this?

{
    "Data": [
        {
            "Id": 11,
            "Name": "Name1"
        },
        {
            "Id": 12,
            "Name": "Name2"
        }
    ]
}

Answer

1. Decode the data.
2. Remove the item from the array.
3. Optionally encode it again as string if needed.

$dataArray = json_decode($data, true);

foreach ($dataArray['Data'] as $key => $item) {
    if ($item['Id'] === 11) {
        unset($dataArray['Data'][$key]);
    }
}

$data = json_encode($dataArray);
