可以通过PHP实现内联动态CSS吗？

I'm looking to dynamically generate some inline CSS and was wondering if it was possible via PHP.

Basically, I'm passing multiple variables via query string and am doing some arithmetic with the values to create values for CSS. Here's what my page looks like:

<?php
$var1 = "var1";
$var2 = "var2";
$divided_amount = $var1/$var1;
?>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
        <title>Derp</title>
</head>
        <div style="height: <?php echo $divided_amount ?>px;">
Dynamic height content here
        </div>

</body>
</html>

This is not working out for me and I'm really trying to avoid going with an external stylesheet if possible.

Any help/insight is very much appreciated!

    You are dividing $var1 with the same variable ($var1). Assuming you actually use numbers and not strings, this will always result in 1. Which means your div element will always be 1px high.

    Secondly, you should ceil() or floor() your result, just to make sure that you are not using floats to set pixel height.

    And remember to validate your HTML - this would have proved that something was wrong.

    Here's a working example:

    <?php
$var1 = "111";
$var2 = "7";
$divided_amount = floor($var1/$var2);
?>
<!DOCTYPE html>
<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
        <title>Derp</title>
    </head>
    <body>

        <div style="height: <?php echo $divided_amount ?>px; background-color: #F2F;">
Dynamic height content here
        </div>

    </body>
</html>
