At the risk of self-embarrassment, could anyone tell me how to use return here:

function dayCount() {

    for ($dayBegin = 1; $dayBegin < 32; $dayBegin++)
    {
      "<option value=\"".$dayBegin."\">".$dayBegin."</option>";
    }
}

My issue is that I am passing this function to Smarty via

$dayCount = dayCount();
$smarty->assign('dayCount', $dayCount);

and

{$dayCount}

but instead the HTML is going straight to the buffer, right before <html> (thanks Hamish), not inside the HTML element I want.

Any help on this?

You need to build up the return statement

function dayCount() {
    $return = array();
    for ($dayBegin = 1; $dayBegin < 32; $dayBegin++)
    {
      $return[] = "<option value=\"".$dayBegin."\">".$dayBegin."</option>";
    }
    return $return;
}

Although this is building up an array like you asked. When outputting it, you would need to implode it.

implode('', $dayCount);

Or otherwise, build up a string instead of an array.

Jacob, you nailed it! Thanks so much for helping - works a treat. I had tried several versions using return but they always output 'array' -- implode was always missing!! – torr Feb 12 '11 at 4:31
