PHP cURL URL Not Found - php

Question

I am new to using cURL....whenever I run this I get a page that says "The requested URL /files/ was not found on this server." But, if I go to the link on a browser then it shows up. Please assist. I have looked at similar questions but could not find a solution to my problem.
<?php
$username="user";
$password="pass";
$url="http://website.com/login/";
$cookie="cookie.txt";
$postdata = "login=$username&pass=$password";
//set the directory for the cookie using defined document root var
$dir = DOC_ROOT;
//the info per user with custom func.
$path = $dir;
//login form action url
$cookie_file_path = $path."/cookie.txt";
$ch = curl_init();
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_NOBODY, false);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie_file_path);
//set the cookie the site has for certain features, this is optional
curl_setopt($ch, CURLOPT_COOKIE, "cookiename=0");
curl_setopt($ch, CURLOPT_USERAGENT,
"Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.7.12) Gecko/20050915 Firefox/1.0.7");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_REFERER, $_SERVER['REQUEST_URI']);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 0);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postdata);
curl_exec($ch);
//page with the content I want to grab
curl_setopt($ch, CURLOPT_URL, "http://website.com/files/");
//do stuff with the info with DomDocument() etc
$html = curl_exec($ch);
echo $html;
curl_close($ch);
?>

Answer 1

$postdata = array(
'login' => $username,
'pass' => $password
);
curl_setopt($ch, CURLOPT_POST, TRUE);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postdata);

Answer 2

Change
curl_setopt($ch, CURLOPT_COOKIE, "cookiename=0");
curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie_file_path);
to
curl_setopt($ch, CURLOPT_COOKIE, $cookie);
curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie);
Make sure you've write permission on the current dir so curl can create the cookie file cookie.txt
you should end-up with something like :
<?php
$username="user";
$password="pass";
$url_login="http://website.com/login/";
$url_files="http://website.com/files/";
$cookie="cookie.txt";
$postdata = "login=$username&pass=$password";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url_login);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie);
curl_setopt($ch, CURLOPT_COOKIE, $cookie);
curl_setopt($ch, CURLOPT_USERAGENT,"Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.7.12) Gecko/20050915 Firefox/1.0.7");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postdata);
curl_exec($ch);
curl_setopt($ch, CURLOPT_URL, $url_files);
$html = curl_exec($ch);
echo $html;
curl_close($ch);
?>
NOTE:
Sometimes, less is more.

Answer 3

The URL you provided http://website.com/files/ has a redirection, so CURL has to have option enabled to follow redirects.
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
While in your code you have
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 0);
0 means false, so you are disabling following on HTTP 30x
