conditional stylesheet

[tomzo]

Howdy,

I have some browser issues that I want to get around using php in my stylesheet. I've been following the technique outlined here, http://www.stylegala.com/articles/no_more_css_hacks.htm. I put this line into my html_header.php file:

<link rel="stylesheet" type="text/css" href="includes/templates/my_template/css/stylesheet.php" />

and renamed the stylesheet.css file so it isn't found. In the stylesheet.php file I dumped my stylesheet between these comments /* BEGIN CSS RENDERING */ and /* END CSS RENDERING */. But when I view the site no styles are being applied though the link is in the source.

Can anyone tell me if I'm missing something.

Here's the stylesheet.php file with cut down css to save scrolling, there's no php in the css as yet as I want to get it displaying first.

<?php
header("Content-type: text/css");
$d = detect();
$b = $d['browser'];
$v = $d['version'];
$o = $d['os'];
function detect()
    {
    $browser = array ("IE","OPERA","MOZILLA","NETSCAPE","FIREFOX","SAFARI");
    $os = array ("WIN","MAC","LINUX");
    $info['browser'] = "OTHER";
    $info['os'] = "OTHER";
    foreach ($browser as $parent)
        {
        $s = strpos(strtoupper($_SERVER['HTTP_USER_AGENT']), $parent);
        $f = $s + strlen($parent);
        $version = substr($_SERVER['HTTP_USER_AGENT'], $f, 5);
        $version = preg_replace('/[^0-9,.]/','',$version);
        if ($s)
            {
            $info['browser'] = $parent;
            $info['version'] = $version;
            }
        }
    foreach ($os as $val)
        {
        if (eregi($val,strtoupper($_SERVER['HTTP_USER_AGENT']))) $info['os'] = $val;
        }
    return $info;
    }
?>

<?php if ($b != "OTHER" && $o != "OTHER" && $v >= 5) { ?>

/* BEGIN CSS RENDERING */

...my css with no php currently

/* END CSS RENDERING */

<?php } ?>

Thanks for any help, I'm stuck on this.
