if( strlen( $x ) == 1 ) $x = '0' . $x;

You were looking for this;

sprintf('%02d', $x)

In fact some further use of sprintf it reduces to

function getDayOptions( $selected )
{
    $options = '';
    $optmask = '<option value="%1$02d"%2$s>%1$02d</option>';

    for( $x = 1; $x < 32; $x++ )
    {
        $selstr = $x == $selected ? ' selected="selected"' : '';
        $options .= sprintf($optmask, $x, $selstr);
    }

    return $options;
}
