A little PHP function that might be helpful

[shannonlp]

I ran across a PHP script that would read your browser and then assign the proper CSS link for the browser.

The orginal version can be found at :

Thought I would share my version. Found it to be helpful for a project that I am working on right now.

This is the core file I named it "browsers.inc.php"


<?php
function load_css() {
$ua_ok= $_SERVER['HTTP_USER_AGENT'];

}

Then in your index.php

top of page

<?php require "browsers.inc.php" ?>


Then within the head tag below
<link href="http://www.yourdomain.com/css/layout.css" rel="stylesheet" type="text/css" />


insert

<?php load_css() ?>


It really helped me hope it can help someone....

Neat script, thanks for sharing... got rep

Question: Shouldn't each code call a different css file? or am i not getting it?

ps, your site took forever to load

[shannonlp]

Thanks,

Yes each css file can be different if needed. You could render a completely different site base on each browser type.

I am upgrading the site and about to move it to a new server. When finished it will have every shopping cart system I have found showing features and overall functionality.
