// Create cURL share handle and set it to share cookie data
$sh = curl_share_init();
curl_share_setopt($sh, CURLSHOPT_SHARE, CURL_LOCK_DATA_COOKIE);
// Initialize the first cURL handle and assign the share handle to it
$ch1 = curl_init("http://example.com/");
curl_setopt($ch1, CURLOPT_SHARE, $sh);
// Execute the first cURL handle
curl_exec($ch1);
// Initialize the second cURL handle and assign the share handle to it
$ch2 = curl_init("http://php.net/");
curl_setopt($ch2, CURLOPT_SHARE, $sh);
// Execute the second cURL handle
// all cookies from $ch1 handle are shared with $ch2 handle
curl_exec($ch2);
// Close the cURL share handle
curl_share_close($sh);
// Close the cURL handles
curl_close($ch1);
