php中foreach结合curl实现多线程的方法分析

$sr=array(url_1,url_2,url_3);foreach ($sr as $k=>$v) { $curlPost=$v.'?f=传入参数'; $ch = curl_init($curlPost) ; curl_setopt($ch, CURLOPT_RETURNTRANSFER, true) ; // 获取数据返回 curl_setopt($ch, CURLOPT_BINARYTRANSFER, true) ; // 在启用 CURLOPT_RETURNTRANSFER 时候将获取数据返回 $data = curl_exec($ch) ; echo $k.'##:'.$data.'<br>';}curl_close($ch);

<?phpmulti_threads_request($nodes){  $mh = curl_multi_init();  $curl_array = array();  foreach($nodes as $i => $url)  {   $curl_array[$i] = curl_init($url);   curl_setopt($curl_array[$i], CURLOPT_RETURNTRANSFER, true);   curl_multi_add_handle($mh, $curl_array[$i]);  }  $running = NULL;  do {   usleep(10000);   curl_multi_exec($mh,$running);  } while($running > 0);  $res = array();  foreach($nodes as $i => $url)  {   $res[$url] = curl_multi_getcontent($curl_array[$i]);  }  foreach($nodes as $i => $url){   curl_multi_remove_handle($mh, $curl_array[$i]);  }  curl_multi_close($mh);  return $res;}print_r(multi_threads_request(array( 'http://www.vevb.com', 'http://sucai.vevb.com',));
