根据PHP中的url限制进入我的网页的请求

Question

I have to restrict the users accessing my webpage based on the url from where the request is coming to my webpage. I am able to get the url from where the request is coming using

$_SERVER['HTTP_REFERER']

As i know the HTTP_REFERER is a header which is sent by the client, most browsers default behavior is to send it, but users can disable it or even send a different referer header. So is there any way to do the proper validation of request based on their url.

Answer 1

Unfortunately, if the user has set the browser to modify the referrer header, there's no way for PHP to discern whether or not the request has come from a certain website.

Blocking traffic from a URL, although easy to do - cannot ever be 100% accurate.
