	       This example will create two cURL handles, add them to a multi handle, and process them asynchronously.

	      <?php
	      // create both cURL resources
	      $ch1 = curl_init();
	      $ch2 = curl_init();

	      // set URL and other appropriate options
	      curl_setopt($ch1, CURLOPT_URL, "http://lxr.php.net/");
	      curl_setopt($ch1, CURLOPT_HEADER, 0);
	      curl_setopt($ch2, CURLOPT_URL, "http://www.php.net/");
	      curl_setopt($ch2, CURLOPT_HEADER, 0);

	      //create the multiple cURL handle
	      $mh = curl_multi_init();

	      //add the two handles
	      curl_multi_add_handle($mh,$ch1);
	      curl_multi_add_handle($mh,$ch2);

	      $active = null;
	      //execute the handles
	      do {
		  $mrc = curl_multi_exec($mh, $active);
	      } while ($mrc == CURLM_CALL_MULTI_PERFORM);

	      while ($active && $mrc == CURLM_OK) {
		  if (curl_multi_select($mh) != -1) {
		      do {
			  $mrc = curl_multi_exec($mh, $active);
		      } while ($mrc == CURLM_CALL_MULTI_PERFORM);
		  }
	      }
