Show a 0 to 5 floating point rating in graphic stars using a PHP function. You can specify which direction to align the graphic stars (left or right)

// Example: ShowInStars(4.3, "left");
function ShowInStars($Rate, $StarImgAlign = "left")
{
        // Remember to change the paths to the star graphics or place them in the Pictures folder
        // You will need three star graphics: one that is off (gray), one that is on (gold) and one that is half on, half off
        $StarOff = "<img src=\"Pictures/StarOff.gif\" align=\"left\" style=\"margin-right: 3px;\" alt=\"-\" />";
        $StarOn = "<img src=\"Pictures/StarOn.gif\" align=\"left\" style=\"margin-right: 3px;\" alt=\"*\" />";
        $StarHalf = "<img src=\"Pictures/StarHalf.gif\" align=\"left\" style=\"margin-right: 3px;\" alt=\"*\" />";
        $TutRate = $Rate;
        $TutRateInt = $TutRate * 10;
        $ModRate = $TutRateInt % 10;
        $TutRateIntFull = $TutRateInt - $ModRate;
        $TutRateIntFull /= 10;
        $TutRateIntFull = round($TutRateIntFull, 0);
        $CountGrayStars = 0;
        $StarsHtml = "";
        if ($Rate > 0)
        {
                if ($ModRate > 5)
                {
                        $CountGrayStars--;
                }
                // If there modulus results in more than half a point paint half a star
                if ($StarImgAlign == "left")
                {
                        $CountGrayStars += 5 - $TutRateIntFull;
                        // Loop to show full stars
                        for ($i = 0; $i < $TutRateIntFull; $i++)
                        {

                        // Show the full star
                        if ($ModRate > 5)
                        {
                                $StarsHtml .= $StarOn;
                        }
                        else if ($ModRate > 0)
                        {
                                $StarsHtml .= $StarHalf;

                }
