follow redirects with curl in php

Question

I know that using cURL i can see the destination URL, pointing cURL to URL having CURLOPT_FOLLOWLOCATION = true.

Example :

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "www.example1.com");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HEADER, true); 
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); 
$result = curl_exec($ch);
$info = curl_getinfo($ch); //Some information on the fetch
curl_close($ch);

$info will have the url of the final destination which can be www.example2.com. I hope my above understanding is correct. Please let me know if not!.

My main question is, what all type of redirection cURL will be able to know? Apache redirect, javascript redirects, form submition redirects, meta-refresh redirects!?

update Thanks for your answeres @ceejayoz and @Josso. So is there a way by which I can follow all the redirect programatically through php?

Answer 1

cURL will not follow JS or meta tag redirects.
