php drop down detect selection

I have a date of birth, and when the user is over Feb (02), the days should go only to 29. As you can see I'm using $month="1" just to test it. I'm supposed to use PHP only, no JavaScript or anything else. How would i go about making that?

<?php
$month="1"; // <-- currently using this to make it 29,30 or 31 days

print "<select name='day'>";
if  ($month==1){
    for ($i=0; $i<=28; $i++)    
    {
        $day = 1 + $i;
        print "<option value = $day>" . $day ."</option>";
    }
}
if  ($month==2){
    for ($i=0; $i<=29; $i++)
    {
        $day = 1 + $i;
        print "<option value = $day>" . $day ."</option>";
    }
}


print "</select>";

print "<select name='month'>";
for ($i=0; $i<=11; $i++)
{

    $month = 1 + $i;
    print "<option value = $month>" .$month ."</option>";
}
print "</select>";

?>

Without Javascript it is just impossible to do.

Once PHP sends stuff to the browser, it is done. It cannot affect the page in any way.

JavaScript, on the other hand, takes over when the browser gets the page. It CAN change the page, and it can even ask the server to do something (in which case PHP may get involved).

In other words, you cannot do what you are asking without JavaScript.
