Multiple CSS Files

[Chris Gwynne]

JUST come up with this concept now

How would I be able to do it so; every time the website refreshes it loads up a new .css file.

For instance, someone goes to "the site" and they'll see a blue layout because it's loaded up the blue.css file. But then the user refreshes and it loads up the pink layout because it loaded up the pink.css file etc etc.

For say a maximum of 10 css files or however many css files are in the css/ directory.

Anyone got any ideas, links to help, or help themselves?

Regards,
Chris

ASSuming you don't want to keep track of the CSS file via cookie/session, you could set up a little code to randomly select which CSS file is written to the head of the page you are serving.

have a file called css.php, with this:

$css = array();
$css[1] = ".text{ font-family...... }";
$css[2] = "more stuff";

if (isset($_COOKIE['css']) && $_COOKIE['css'] < count($css))
{
echo $css[$_COOKIE['css']];
$new = $_COOKIE['css'] + 1;
set_cookie("css", $new, time() + * 3600 * 24 * 365
}
else
{
echo $css[1];
setcookie("css", "1", time() + 3600 * 24 * 365);
} 

Then call it by "css.php" (linking it, or just putting an include with PHP.)

It'll go through them.

how to do it with css files

Funny I didn't think of this but now you say it it really sounds nice...
lets see

$cssfiles = array();
$handle =opendir($directory); // open the directory
while ($file = readdir($handle)) 
{
 if (($file != ".") && ($file != "..") ) 
 {
  $cssfiles[$i] = $file;
  $i++;
 }
 
// now all the css files are in 1 array
closedir($handle);  // closedir
reset($cssfiles);
 
srand ((float)microtime()*1000000); // get random
shuffle ($cssfiles); //lets shuffle the deck
// now just use $cssfiles[0] cause it's different everytime 
 
echo $cssfiles[0];

It's different, but it's not ordered, so you could end up having the same ones more than once in a row if there are only 2 or 3.

However adding:

$cssfiles = array();
$handle =opendir($directory); // open the directory
while ($file = readdir($handle)) 
{
if (($file != "." ) && ($file != ".." ) ) 
{
  $cssfiles[$i] = $file;
  $i++;
} 

Into my cookie code should work well.

while ($file = readdir($handle)) 

should be

while (false !== ($file = readdir($handle))) 

(check www.php.net/readdir for an explaination)
