如何阻止IE 10及以下[复制]

Question

This question already has an answer here:

• PHP: If internet explorer 6, 7, 8 , or 9 17 answers

I'm having issues with IE 10, 9, 8 and below. (Tested with IE Tester). But my layout works on IE 11. I already have a page that recommends a user to upgrade their browser to IE 11 or use another browser. However, I don't have a code that redirects users to this recommendation page. I want to do it using PHP.

So, to sum it up:

What am I finding?: A PHP code that redirects users to a particular recommendation page.

If I did understood your question correctly,

Put this on the very top of your PHP file, this code will detect IE 10 and below, and redirect them to your recommendation page:

if(preg_match('/(?i)msie [1-9]/',$_SERVER['HTTP_USER_AGENT']))
{
    header( 'Location: recommendation.php' ) ;
}
