PHP-তে JSON নিয়ে কাজ করা

$user = [
    'name' => 'Sam',
    'age' => 28,
    'active' => true,
];

echo json_encode($user);
// {"name":"Sam","age":28,"active":true}

echo json_encode($user, JSON_PRETTY_PRINT);

$json = '{"name":"Sam","age":28}';

$object = json_decode($json);
echo $object->name;        // Sam — object access

$array = json_decode($json, true);
echo $array['name'];        // Sam — array access

header('Content-Type: application/json');

$users = getUsersFromDatabase();   // associative array-এর একটি array

echo json_encode([
    'success' => true,
    'data' => $users,
]);

$data = json_decode($json);
if (json_last_error() !== JSON_ERROR_NONE) {
    die('Invalid JSON: ' . json_last_error_msg());
}
