cURL doesn't set a cookie anymore, but why?

My cURL script does not work anymore (so keep in mind it DID work before) on my localhost (so it DOES work on my external host, hence: it might be the server settings):

This script worked fine before on my localhost (it still does on my host). Nothing changed.

REAL PROBLEM: cURL does not set a cookie! What apache modules should be ON for writing cookies (in a .txt file)? I'm running wampserver.

Please note I'm already using:

    curl_setopt($curlTable, CURLOPT_COOKIEJAR, 'cookie.txt');
    curl_setopt($curlTable, CURLOPT_COOKIEFILE, 'cookie.txt');

And that php.ini is:

extension=php_curl.dll is uncommented

Other information:

Currently using:

$postFields = array(
    'user'     => $userNum,
    'paswoord' => $userPass,
    'login'    => 'loginform',
    'csrf'     => $token[1]);

// 'user='.$userNum.'&paswoord='.$userPass.'&login=loginform&csrf='.$token[1]

$postData = http_build_query($postFields);

    $curlTable = curl_init();
    curl_setopt($curlTable, CURLOPT_URL, 'link');
    curl_setopt($curlTable, CURLOPT_COOKIEJAR, 'cookie.txt');
    curl_setopt($curlTable, CURLOPT_COOKIEFILE, 'cookie.txt');
    curl_setopt($curlTable, CURLOPT_ENCODING, 'gzip');
    curl_setopt($curlTable, CURLOPT_RETURNTRANSFER, true); 
    curl_setopt($curlTable, CURLOPT_POST, true);
    $tableData = curl_exec($curlTable);
    if (!$tableData) echo 'post problem?'.$tableData;
    if ($tableData == false)
{
    echo 'Curl error: ' . curl_error($curlTable);
}

    curl_close($curlTable);
// Here I further process my data.

I got this issue while migrating a script from PHP7 to PHP8

Prior to PHP8, the cookie wasn't set if we didn't call explicitely curl_close($handle).

With PHP8, this function has no effect anymore. We need to call unset($handle); to remove the CurlHandle object. Then, the cookie file is finally created.

Although this question is kind of outdated, i got the same problem today and did not solve it with any of the suggestions here. The reason the cookies were not saved was simply the missing call of

curl_close()

If curl_close is not called after the curl request cookies are NOT saved.

Took me about an hour to find out.... maybe saves your time :-)

In my situation there been two problems: 1) Server did not accepted cookie without value 2) I did not used CURLOPT_COOKIEFILE option

Every problem solves by dividing it on separate parts and solve each of it by itself.

So I recommend you to divide your problem: 1) Check is this COOKIEFILE problem or website - send cookie value directly without file - may be there is server problem 2) If this will be ok - check file contents may be there is something wrong (like in my situation)

Probably you was banned at the login process. This will give you more info about the problem:

// change 
// if (!$siteSource) echo 'Help!';
// to
if ($siteSource === false)
{
    echo 'Curl error: ' . curl_error($curl);
}

EDIT: some other opt that you can try (SSL related solved my problems more that one time):

curl_setopt($curl, CURLOPT_USERAGENT, 'Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; .NET CLR 1.0.3705; .NET CLR 1.1.4322; Media Center PC 4.0)');
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($curl, CURLOPT_VERBOSE, 1);

// following is very important
// TRUE to follow any "Location: " header that the server sends
// as part of the HTTP header (note this is recursive, PHP will follow
// as many "Location: " headers that it is sent, unless CURLOPT_MAXREDIRS is set).
curl_setopt($curl, CURLOPT_FOLLOWLOCATION, true);

EDIT 2: Following opt will give you the headers returned (use only to debug). Besides be sure about the cookie.txt is being used properly (locatable and writable).

curl_setopt($curl, CURLOPT_HEADER, true);

That's all I can contribute by my side. Now lo lunch!

EDIT 3: Cookie related stuff:

$cookie_file = PATH_TO_YOUR_COOKIE_FILE . '/cookie.txt';

if (! file_exists($cookie_file) || ! is_writable($cookie_file))
{
    echo 'Cookie file missing or not writable.';
    exit;
}

// you already added the following, I put it again just to remark their utility
curl_setopt($curl, CURLOPT_COOKIEFILE, $cookie_file);
curl_setopt($curl, CURLOPT_COOKIEJAR, $cookie_file);

EDIT 4: Always check this at the beginning:

if ( ! extension_loaded('curl'))
{
    echo "You need to load/activate the curl extension.";
}

If you receive this error, activate curl in php.ini uncommenting/removing the front ;

windows:
;extension=php_curl.dll // or curl.dll
linux:
;extension=php_curl.so // or curl.so

and restart the web server. If you do not found this line then you need install curl:

// ubuntu
sudo apt-get install php5-curl

// centos
sudo yum install php5-curl

For windows or your wampserver it must be easy too.

There are two things I can see that are wrong with that code:

You switch variables names between creating the resource and executing it:

$curl = curl_init();                 // $curl
$siteSource = curl_exec($curlTable); // $curlTable

You made a post request but didn't set a content type, you should do this:

$postFields = array(
  'user' => $userNum,
  'paswoord' => $userPass,
  'login' => 'loginform'
);
// This ensures all strings are properly encoded
$postData = http_build_query($postFields);

// ...

// curl *should* do this by itself, but best to do it explicitly
curl_setopt($curl, CURLOPT_HTTPHEADER, array(
  'Content-Type: application/x-www-form-urlencoded',
  'Content-Length: '.strlen($postData),
  'Connection: close'
));
