10. }
11. $running = NULL;
12. do {
13. usleep(10000);
14. curl_multi_exec($mh,$running);
15. } while($running > 0);
17. $res = array();
18. foreach($nodes as $i => $url)
19. {
20. $res[$url] = curl_multi_getcontent($curl_array[$i]);
21. }
23. foreach($nodes as $i => $url){
24. curl_multi_remove_handle($mh, $curl_array[$i]);
25. }
26. curl_multi_close($mh);
27. return $res;
