Hello, how can I use HTTP_USER_AGENT to detect their browser (or any other code to detect a visitor's browser) and for it to only continue to if the user is using any version of internet explorer. I was thinking of something like
if (HTTP_USER_AGENT != "something") {
echo "You must use Internet Explorer!";
} else {
}
but I don't know what value I should put there.
Thanks,
Darko
