for循环php中的动态变量

i have this code and works fine to get the stats of january:

$home = 5;
    $get_jan = $db->prepare('SELECT * FROM cars WHERE home = :home AND month = :month');
    $get_jan->bindParam(':home',$home);
    $get_jan->bindParam(':month',$janu);
    $get_jan->execute();

i want to make some statistics so i need to do that for 12 months. Instead of writing this code for the 12 months separately how can i use a for loop? i tried something like this with no success:

$home = 5;
for($i=1;$i=12;$i++){
$get.$i = $db->prepare('SELECT * FROM cars WHERE home = :home AND month = :month');
$get.$i->bindParam(':home',$home);
$get.$i->bindParam(':month',$i);
$get.$i->execute();
}

Any idea how can be done?

    That Works finally:

    $home = 5;
    for($i=1;$i<=12;$i++){
    $get[$i] = $db->prepare('SELECT * FROM cars WHERE home = :home AND month = :month');
    $get[$i]->bindParam(':home',$home);
    $get[$i]->bindParam(':month',$i);
    $get[$i]->execute();
    }
