今天就跟大家聊聊有关怎么在php中利用 curl批处理实现可控并发异步操作，可能很多人都不太了解，为了让大家更加了解，小编给大家总结了以下内容，希望大家根据这篇文章可以有所收获。
<?php

function callback($response, $info, $error, $request)
{
echo 'response:<br>';
print_r($response);
echo '<br>' . date("Y-m-d H:i:s") . ' <br>';
echo '<br>' . str_repeat("-", 100) . '<br>';
}
$USER_COOKIE = (!empty($_REQUEST['cookie'])) ? $_REQUEST['cookie'] : file_get_contents("cookie.txt");
$curl = new Curl ("callback");
$data = array(
array(
'url' => 'http://dyactive2.vip.xunlei.com/com_sign/?game=qmr&type=rec_gametime&referfrom=&rt=0.42521539455332336', //秦美人

foreach ($data as $val) {
$request = new Curl_request ($val ['url'], $val ['method'], $val ['post_data'], $val ['header'], $val ['options']);
$curl->add($request);
}
$curl->execute();
echo $curl->display_errors();使用下来效果很好，没有副作用，并发数可控，应用之处多多，自己发挥想象吧
