telnet上的顺序多卷曲请求

Question

我在localhost上的一个端口上发出一个多卷曲请求。但是这些调用正在顺序执行。但是，当我从其他主机发出这些请求时，这些调用将并行执行..

请帮助我...我正在编写下面的代码：

<?php
// create both cURL resources
$ch1 = curl_init();
$ch2 = curl_init();

// set URL and other appropriate options
curl_setopt($ch1, CURLOPT_URL, "telnet://127.0.0.1:10000");
curl_setopt($ch1, CURLOPT_HEADER, 0);
curl_setopt($ch1, CURLOPT_PROTOCOLS, CURLPROTO_TELNET);
curl_setopt($ch2, CURLOPT_URL, "telnet://127.0.0.1:10000");
curl_setopt($ch2, CURLOPT_HEADER, 0);
curl_setopt($ch2, CURLOPT_PROTOCOLS, CURLPROTO_TELNET);


$mh = curl_multi_init();

//add the two handles
curl_multi_add_handle($mh,$ch1);
curl_multi_add_handle($mh,$ch2);

$active = null;
//execute the handles
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);
    }
}

//close the handles
curl_multi_remove_handle($mh, $ch1);
curl_multi_remove_handle($mh, $ch2);
curl_multi_close($mh);
