php_value auto_prepend_file none
php_value default_mimetype “text/css”
SetHandler application/x-httpd-php

Where you load the style.css file put this:

style.css?MODIFIED_TIME

I could see doing this php trick when different browsers need different styles. But you could as easily use different style sheets for different browsers and actively set the variable in config.php accordingly. Do that for the part that MUST be different, and use a single common stylesheet for the rest that doesn’t matter which browser is used.

The best thing to do is leave the stylesheets static. If you need to add dynamic style information, include it in the actual web page in style tags.

cigraphics is on the right track for re-generating static style sheets when changes are made to the website, but then you have to worry about browsers caching their CSS sheets because they are expected to be static. I know there are workarounds for that, but why worry about it? Just include any dynamic content in the main web page.

function css() {
	$bg = "red";
	$color = "green";
	$txt = "Arial";

	$css = <<<EOF
body {background-color: $bg; font: $color $txt;}
EOF;
	return $css;
}
$x = css();
file_put_contents('style.css', $x);

Add it to your administration panel and when you change the values it will rewrite the style.css file and that’s it. You won’t need to call it every time you enter the site. And if you want to change the styles you can make more files like style_blue.css, style_red.css …etc

I found a solution for setting only a specific file to be processed:

You would need the MIME override if it was a .php file.

You can then use for example link rel=”stylesheet” href=”mystyle.php”

The browser is not interested in the fileextension, only the server uses them sometimes. And i can see what is php, there is no need to work with .htaccess and its also a bit more serverfriendly because most css files get delivered directly.

Thereby you still have the option of using a static .css file when no php is needed in your style sheets, for better performance.
