Taking out all the redundancy, using proper prepared statements (assuming PDO) and adding error handling (at least a stub), you end up with this:

$stmt = $conn->prepare('SELECT name, age, address, pincode FROM json WHERE name = ?');
$stmt->execute(array('peter'));

if ($row = $stmt->fetch(PDO::FETCH_ASSOC)) {
    echo json_encode($row);
} else {
    echo json_encode(array('status' => 'error'));
}

If you expect multiple rows:

echo json_encode($stmt->fetchAll(PDO::FETCH_ASSOC));
