a simple way of using imagerectangle to create a percentage bar

<?php
//this needs to reside in its own php page
//you can include that php page in your html as you would an image:
//<IMG SRC="ratingpng.php?rating=25.2" border="0">

function drawRating($rating) {
    $image = imagecreate(102,10);
    $back = ImageColorAllocate($image,255,255,255);
    $border = ImageColorAllocate($image,0,0,0);
    $red = ImageColorAllocate($image,255,60,75);
    $fill = ImageColorAllocate($image,44,81,150);
    ImageFilledRectangle($image,0,0,101,9,$back);
    ImageFilledRectangle($image,1,1,$rating,9,$fill);
    ImageRectangle($image,0,0,101,9,$border);
    imagePNG($image);
    imagedestroy($image);
}

Header("Content-type: image/png");
drawRating($rating);

?>
