Keeping cookies without using curl's cookie jar files... Lycos Mail, IndiaTimes, Rediffmail address book import scripts

Free code...

You can support development of more free scripts by purchasing the full package of my php address book importing scripts. There are more than 100 websites (some of them are big names) worldwide that have already integrated my scripts with their cms and online community websites. While my scripts might not be the cheapest right now I do my best to provide top notch quality, and unlike many other websites that resell scripts made by others, I have actually developed every single line of code that I offer myself and I am able to provide quick updates whenever necessary.

This is actually only part of the code that I use for my import scripts. It is a very essential part of the code because it allows for keeping all cookies in a string/array instead of storing them in curl's cookie jar files (also it automatically updates your $ch object with the new cookies so you don't even need to worry about that).

I am releasing this part of the code due to some people trying to claim this as their own code (even as part of "their" import scripts!). There are much bigger chunks of my code sitting out there with someone else's name on it and I really do not appreciate that. The code below (or anything that's very close to it) has been originally used in my scripts and is developed by me.

I developed most of it back in January 2006 and I haven't made any major changes ever since because it has been working perfectly for all this time:

function read_header($ch, $string)
{
    global $location;
    global $cookiearr;
    global $ch; 
       # ^overrides the function param $ch
       # this is okay because we need to 
       # update the global $ch with 
       # new cookies
    
    $length = strlen($string);
    if(!strncmp($string, "Location:", 9))
    {
      $location = trim(substr($string, 9, -1));
    }
    if(!strncmp($string, "Set-Cookie:", 11))
    {
      $cookiestr = trim(substr($string, 11, -1));
      $cookie = explode(';', $cookiestr);
      $cookie = explode('=', $cookie[0]);
      $cookiename = trim(array_shift($cookie)); 
      $cookiearr[$cookiename] = trim(implode('=', $cookie));
    }
    $cookie = "";
    if(trim($string) == "") 
    {
      foreach ($cookiearr as $key=>$value)
      {
        $cookie .= "$key=$value; ";
      }
      curl_setopt($ch, CURLOPT_COOKIE, $cookie);
    }

    return $length;
}

curl_setopt($ch, CURLOPT_HEADERFUNCTION, 'read_header');

Some of the code here is provided for free, however I do ask you to link to me on the section of your site where you use the scripts.
