今天就跟大家聊聊有關怎么在php中利用 curl批處理實現可控并發異步操作,可能很多人都不太了解,為了讓大家更加了解,小編給大家總結了以下內容,希望大家根據這篇文章可以有所收獲。
<?php include 'curl.class.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 'method' => 'POST', 'post_data' => '', 'header' => null, 'options' => array( CURLOPT_REFERER => "http://niu.xunlei.com/entergame/?gameNo=qmr&fenQuNum=3", CURLOPT_COOKIE => $USER_COOKIE, ) ), array( 'url' => 'http://dyactive2.vip.xunlei.com/com_sign/?game=sq&type=rec_gametime&referfrom=&rt=0.42521539455332336', //神曲 'method' => 'POST', 'post_data' => '', 'header' => null, 'options' => array( CURLOPT_REFERER => "http://niu.xunlei.com/entergame/?gameNo=sq&fenQuNum=41", CURLOPT_COOKIE => $USER_COOKIE, ) ), array( 'url' => 'http://dyactive2.vip.xunlei.com/com_sign/?game=frxz&type=rec_gametime&referfrom=&rt=0.42521539455332336', //凡人修真 'method' => 'POST', 'post_data' => '', 'header' => null, 'options' => array( CURLOPT_REFERER => "http://niu.xunlei.com/entergame/?gameNo=frxz&fenQuNum=3", CURLOPT_COOKIE => $USER_COOKIE, ) ), array( 'url' => 'http://dyactive2.vip.xunlei.com/com_sign/?game=smxj&type=rec_gametime&referfrom=&rt=0.42521539455332336', //神魔仙界 'method' => 'POST', 'post_data' => '', 'header' => null, 'options' => array( CURLOPT_REFERER => "http://niu.xunlei.com/entergame/?gameNo=smxj&fenQuNum=2", CURLOPT_COOKIE => $USER_COOKIE, ) ), array( 'url' => 'http://dyactive2.vip.xunlei.com/com_sign/?game=qsqy&type=rec_gametime&referfrom=&rt=0.42521539455332336', //傾世情緣 'method' => 'POST', 'post_data' => '', 'header' => null, 'options' => array( CURLOPT_REFERER => "http://niu.xunlei.com/entergame/?gameNo=qsqy&fenQuNum=11", CURLOPT_COOKIE => $USER_COOKIE, ) ), ); foreach ($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();
使用下來效果很好,沒有副作用,并發數可控,應用之處多多,自己發揮想象吧
