Is one of the following functions better than the other, in terms of where to place the 'return false' statement?

Function #1:

function equalToTwo($a, $b)
{
    $c = $a + $b;
    if($c == 2)
    {
        return true;
    }
    return false;
}

Function #2:

function equalToTwo($a, $b)
{
    $c = $a + $b;
    if($c == 2)
    {
        return true;
    }
    else
    {
        return false;
    }
}

Thanks!
