This example will create a cURL share handle, add two cURL handles to it,
     and then run them with cookie data sharing.
    
       <?php
 // 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 );
 curl_close ( $ch2 );
