强制用户使用Chrome / FireFox而不是IE

Question

I have a website build using PHP and HTML. If a user browses my website using IE, I want to display a message saying: "Please use Firefox or Google Chrome" instead of rendering the index page.

Is it possible? If so how could it be done?

Please note I am not that advanced with PHP.

Thanks.

You could also do it like this:

<?php 
function using_ie(){
    $user_agent = $_SERVER['HTTP_USER_AGENT'];
    $ub =false;
    if(preg_match('/MSIE/i',$user_agent))
    {$ub = true;}
    return $ub;
}


if(using_ie()==true){
    //Show notice
}else{
    //Cont
}

?>

Dont forget that that IE users still own 30% of the market share meaning 1 in 3.3 of your users will be using IE http://www.w3counter.com/globalstats.php
