But, your codes still dont work:( I found the answer by putting the following code: ... while ($mrc == CURLM_CALL_MULTI_PERFORM); #fix if(strtoupper(substr(PHP_OS,0,3)) === 'WIN'){ curl_multi_select($this->m_handle, 0.005); curl_multi_exec($this->m_handle, $active); } ... ------------------------------------------------------------------------ [2012-12-13 16:43:05] cristian dot marfil at gmail dot com Works for me! // jlcooke - thanks to http://technosophos.com/content/connection-sharing-curl- php-how-re-use-http-connections-knock-70-rest-network-time // https://forums.aws.amazon.com/thread.jspa?messageID=397448 class RequestCore { public static $curl_multi_handle = null; public static function curlExecUsingMulti($curl_handle) { set_time_limit(1); //Test // Create a multi if necessary. if (empty(RequestCore::$curl_multi_handle)) { RequestCore::$curl_multi_handle = curl_multi_init(); } // Add the handle to be processed. curl_multi_add_handle(RequestCore::$curl_multi_handle, $curl_handle); // Do all the processing. $active = NULL; do { $ret = curl_multi_exec(RequestCore::$curl_multi_handle, $active); } while ($ret == CURLM_CALL_MULTI_PERFORM); while ($active && $ret == CURLM_OK) { //FIX https://bugs.php.net/bug.php?id=60790&edit=1 by pierrick@php.net if (curl_multi_select(RequestCore::$curl_multi_handle) == -1) { usleep(100); } //if (curl_multi_select(RequestCore::$curl_multi_handle) != -1) { do { $mrc = curl_multi_exec(RequestCore::$curl_multi_handle, $active); } while ($mrc == CURLM_CALL_MULTI_PERFORM); //} } // Remove the handle from the multi processor. curl_multi_remove_handle(RequestCore::$curl_multi_handle, $curl_handle); return curl_multi_getcontent($curl_handle); } } ------------------------------------------------------------------------ [2012-09-22 13:34:53] pierrick@php.net This behavior is probably related to Bug #61141. Can you try this script $ch1 = curl_init(); curl_setopt_array($ch1, array(CURLOPT_URL=>"http://lxr.php.net/", CURLOPT_HEADER=>0, CURLOPT_RETURNTRANSFER=>1)); $mh = curl_multi_init(); curl_multi_add_handle($mh,$ch1); $active = null; do $mrc = curl_multi_exec($mh, $active); while ($mrc == CURLM_CALL_MULTI_PERFORM); $start_time = microtime(true); while ($active && $mrc == CURLM_OK) { if (curl_multi_select($mh) == -1) { usleep(100); } do $mrc = curl_multi_exec($mh, $active); while ($mrc == CURLM_CALL_MULTI_PERFORM); } curl_multi_remove_handle($mh, $ch1); curl_multi_close($mh); And let me know if you still have your problem ? ------------------------------------------------------------------------ [2012-04-03 16:27:11] bompus at gmail dot com Possibly related to 61141 and 61240 ------------------------------------------------------------------------ [2012-03-24 07:28:59] qiwei dot mo at gmail dot com I have the same problem white them. Env: win7 + php5.4.0 Use the code as curl_multi-exec http://cn2.php.net/manual/zh/function.curl-multi-exec.php cause the final error: Fatal error: Maximum execution time of 30 seconds exceeded. But it be runing well in php5.3.6 In PHP5.4 , when i replace the under code ----------------------------------- $active = null; // 执行批处理句柄 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); } } -------------------------------------- With do { curl_multi_exec($hMultiCurl, $iRunning); } while ($iRunning > 0); ------------------------------------- the programe run ok So the question is the curl_multi_select bug , cause the while infinite loop. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
