远程登录并使用PHP中的cURL显示内容

Question

I am using cURL in PHP to login to a remote server of mine. I have successfully logged in the remote URL but I cannot seem to display the content of that page. Here is my code so far:

<?php

$username = 'Blah';
$password = 'BlahBlah';

$ch = curl_init();
$postdata="email=$username&password=$password";
curl_setopt ($ch, CURLOPT_URL,"http://www.example.com/login.php");
curl_setopt ($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt ($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.6) Gecko/20070725 Firefox/2.0.0.6");
curl_setopt ($ch, CURLOPT_HEADER, true);
curl_setopt ($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_COOKIEJAR, 'cookie.txt');
curl_setopt ($ch, CURLOPT_COOKIEFILE, 'cookie.txt');
curl_setopt ($ch, CURLOPT_REFERER, "http://www.example.com/login.php");
curl_setopt ($ch, CURLOPT_POSTFIELDS, $postdata);
curl_setopt ($ch, CURLOPT_POST, 1);
$result = curl_exec($ch);

curl_setopt($ch, CURLOPT_URL, "http://www.example.com/User/Home.php") ;
$result2 = curl_exec($ch) ;

echo $result2 ;

curl_close($ch);

?>

When I try echoing $result2, nothing is there. Nothing is printed to the screen. What do I need to do in order to have the content printed to the screen?

Here is the HTTP Header output:

Answer 1

It probably isn't following redirects. use:

curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
