PHP curl_multi_add_handle() 函数：如何高效管理多个cURL句柄会话

resource curl_multi_add_handle ( resource $mh, resource $ch )

<?php
// 初始化一个cURL会话句柄
$mh = curl_multi_init();
<p>// 创建第一个cURL句柄<br>
$ch1 = curl_init();<br>
curl_setopt($ch1, CURLOPT_URL, "<a rel="noopener" target="_new" class="" href="https://www.example.com/api1">https://www.example.com/api1</a>");<br>
curl_setopt($ch1, CURLOPT_RETURNTRANSFER, true);</p>
<p>// 将第一个cURL句柄添加到会话中<br>
curl_multi_add_handle($mh, $ch1);</p>
<p>// 创建第二个cURL句柄<br>
$ch2 = curl_init();<br>
curl_setopt($ch2, CURLOPT_URL, "<a rel="noopener" target="_new" class="" href="https://www.example.com/api2">https://www.example.com/api2</a>");<br>
curl_setopt($ch2, CURLOPT_RETURNTRANSFER, true);</p>
<p>// 将第二个cURL句柄添加到会话中<br>
curl_multi_add_handle($mh, $ch2);</p>
<p>// 循环执行直到所有请求完成<br>
do {<br>
$status = curl_multi_exec($mh, $running);<br>
} while ($status === CURLM_CALL_MULTI_PERFORM || $running);</p>
<p>// 获取第一个请求的结果<br>
$response1 = curl_multi_getcontent($ch1);<br>
echo "Response 1: " . $response1;</p>
<p>// 获取第二个请求的结果<br>
$response2 = curl_multi_getcontent($ch2);<br>
echo "Response 2: " . $response2;</p>
<p>// 关闭会话句柄<br>
curl_multi_remove_handle($mh, $ch1);<br>
curl_multi_remove_handle($mh, $ch2);<br>
curl_multi_close($mh);<br>
