Best star rating solution for PHP

[Darkwolf]

I'm wondering what the best and most efficient way to write up the following PHP code would be?\[code\] if ($av == 1) echo '/images/1-star.png'; if ($av > 1 && < 2) echo '/images/1-half-star.png'; if ($av == 2) echo '/images/2-star.png'; if ($av > 2 && < 3) echo '/images/2-half-star.png';\[/code\]Following this same pattern up to 5 stars.
