Android Передача параметров в MySQL JSON — Listview

Сейчас я использую PHP-скрипт, который возвращает данные из моей базы данных.

Ниже мой php скрипт с закомментированной информацией. Как вы можете видеть, я жестко прописываю диету в = 1. Я хотел бы передать в сценарий диету из моей деятельности при запуске скрипта. Весь мой код работает нормально, и данные отображаются в моем списке просмотра, как я могу передать dietid?

заранее спасибо

$con = mysqli_connect($host, $user, $pwd, $db);if(mysqli_connect_errno($con)) {
die("Failed to connect to MySQL: " . mysqli_connect_error());
}$dietid = array( $_GET['dietid'] );
$sql = "SELECT * FROM food WHERE dietid =".$dietid;
$result = mysqli_query($con, $sql);$rows = array();while($row = mysqli_fetch_array($result, MYSQLI_ASSOC)) {
$rows[] = $row;
}mysqli_close($con);

echo json_encode($rows);
