Question

I need to get the URL of a redirected page in PHP.

Let’s say I have an URL like http://example.com, while I open this, it redirects to http://redirected_url.com. So the input and output of this PHP function must be like this:

• Input: http://example.com
• Output: http://redirected_url.com

How can I do this?

Edit: I don’t mean redirection. I need the url of redirected page. So I don’t know redirected url, but I need to find it.

It’s hard to tell from the question, but if you’re wanting to tell if a url you’re accessing is trying to redirect you, you can use get_headers("http://some_url") and check in key[0] of the response if it’s sent you a 301 status code. Or if it has a “location” header like is mentioned above. php docs

Like this:

function get_redirect_target($destination){
    $headers = get_headers($destination, 1);
    return $headers['Location'];
}

I’ll leave error (and case sensitivity) handling up to you, but that should get you there
