php 中curl 循环往请求多个URL和多线程去请求多个URL的方法
php 中curl 循环去请求多个URL和多线程去请求多个URL的方法
第一种:循环请求
$sr=array(url_1,url_2,url_3); foreach ($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);
第二种 多线程请求
$sr=array(url_1,url_2,url_3);
$mh = curl_multi_init(); foreach ($sr as $i => $url) { $curlPost=$url.'?f=%2Fpipefile%2Fskincss%2Fskincss_1356490012_1.zip%40%2Fskincss%2Fimages%2Fskincss_1356490012_1.jpg'; $conn[$i]=curl_init($curlPost); curl_setopt($conn[$i],CURLOPT_RETURNTRANSFER,1); curl_multi_add_handle ($mh,$conn[$i]); } do { $mrc = curl_multi_exec($mh,$active); } while ($mrc == CURLM_CALL_MULTI_PERFORM); while ($active and $mrc == CURLM_OK) { if (curl_multi_select($mh) != -1) { do { $mrc = curl_multi_exec($mh, $active); } while ($mrc == CURLM_CALL_MULTI_PERFORM); } } foreach ($sr as $i => $url) { $res[$i]=curl_multi_getcontent($conn[$i]); curl_close($conn[$i]); } var_dump($res);
简单测试 后 发现,同时请求4个不同的URl,循环的处理速度 好像比多线程的快,这个问题有待验证
