使用php html生成条形图使百分比正确显示?

Can anyone help me out im trying to do a simple code with php and html, my goal is to get my variable via database and post the number and add a % at the end but with my code it's confusing to me.

The very last one works but its hardcoded.

Click here for image. http://i.stack.imgur.com/0Apoh.png The yellow graph i wat to dispay at 55% and the rest wont be filled in such as the bottom graph.

<style type="text/css">
    .red {background-color: red;}
    .green {background-color: green;}
    .yellow{background-color: yellow;}
    .bar { width: 15%; border: 1px solid #000; background: grey; }
    </style>


    <?php   
    if ($percentage >= 51 && $percentage <= 74) {
    echo "<div class=\"bar\" align=\"left\"><div class=\"yellow\" style=\"width: $percentage %\">$percentage test</div></div>";
    } else if ($percentage >= 75){
    echo "<div class=\"bar\" align=\"left\"><div class=\"green\" style=\"width: $percentage \"%\">$percentage test</div></div>";
    } else if ($percentage >= 0 && $percentage <= 50) {
    echo "<div class=\"bar\" align=\"left\"><div class=\"red\" style=\"width:46%\">$percentage test</div></div>";
    }
    ?>
