如何将我的 cURL function 转换为 curl_multi？

Question

我有这个 function，它返回 JSON 中的数据，然后我用 fetch() 返回到 HTML

但我想知道如何实现curl_multi_init以便请求不仅在example.com/api1/上进行，还要添加另一个 URL 并避免第一个 URL 饱和。

我希望我能很好地解释自己。 我希望 cURL 请求在 URL 1 和 URL2 之间随机交替。 因为它们是相同的 API 但在不同的链接中。 类似于： $curl = curl("https://example.com/api1/", "https://example.com/api2/". $dataNumber);

代码：

<?php
//function
function curl($url, $var = null)
{
    $curl = curl_init($url);
    curl_setopt($curl, CURLOPT_TIMEOUT, 25);
    curl_setopt($curl, CURLOPT_TCP_FASTOPEN, true);
    if ($var != null) {
        curl_setopt($curl, CURLOPT_POST, true);
        curl_setopt($curl, CURLOPT_POSTFIELDS, $var);
    }
    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, true);
    curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, 2);
    curl_setopt($curl, CURLOPT_SSLVERSION, CURL_SSLVERSION_TLSv1_2);
    curl_setopt($curl, CURLOPT_PROTOCOLS, CURLPROTO_HTTPS);
    curl_setopt($curl, CURLOPT_FOLLOWLOCATION, false);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
    if (defined('CURLOPT_DOH_URL')) {
        curl_setopt($curl, CURLOPT_DOH_URL, 'https://cloudflare-dns.com/dns-query');
        }
    $result = curl_exec($curl);
    curl_close($curl);
    return $result;
}
//getting number
function getNumber($dataNumber)
{
    return substr($dataNumber, 0, 6);
}
$format = $num . "|" . $data1 . "|" . $data2 . "|" . $data3;
$dataNumber = getNumber($num);
$curl = curl("https://example.com/api1/" . $dataNumber);
$json = json_decode($curl);
$brnd = $json->data->vendor ? $json->data->vendor : "N/A";
$type = $json->data->type ? $json->data->type : "N/A";
$ctgry = $json->data->level ? $json->data->level : "N/A";
$country = $json->data->countryInfo->name ? $json->data->countryInfo->name : "N/A";
$number = $json->data->bin ? $json->data->bin : "N/A";
$genInfo =
    "<span>" .
    $number .
    "</span> - <span>" .
    $brnd .
    "</span> - <span>" .
    $type .
    "</span> - <span>" .
    $ctgry .
    "</span> - <span>" .
    $country .
    "</span>";
//using the received data
$fechamal = array('info' => 'good', 'real' => '<span>REAL</span> | ' . $format . " <strong>[DATA: " . $genInfo . ']</strong>');

This is my attempt, after adapting the function for multicurl, I have no idea how to return the result:( I am new to PHP. My forte is Javascript and I am just learning PHP.

<?php
//function
function curl($url, $var = null)
{
    $curl = curl_init($url = "https://example.com/api1/");
    $curl2 = curl_init($url = "https://example.com/api2/");
    curl_setopt($curl, CURLOPT_TIMEOUT, 25);
    curl_setopt($curl, CURLOPT_TCP_FASTOPEN, true);
    if ($var != null) {
        curl_setopt($curl, CURLOPT_POST, true);
        curl_setopt($curl, CURLOPT_POSTFIELDS, $var);
    }
    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, true);
    curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, 2);
    curl_setopt($curl, CURLOPT_SSLVERSION, CURL_SSLVERSION_TLSv1_2);
    curl_setopt($curl, CURLOPT_PROTOCOLS, CURLPROTO_HTTPS);
    curl_setopt($curl, CURLOPT_FOLLOWLOCATION, false);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
    //dos
    curl_setopt($curl2, CURLOPT_TIMEOUT, 25);
    curl_setopt($curl2, CURLOPT_TCP_FASTOPEN, true);
    if ($var != null) {
        curl_setopt($curl2, CURLOPT_POST, true);
        curl_setopt($curl2, CURLOPT_POSTFIELDS, $var);
    }
    curl_setopt($curl2, CURLOPT_SSL_VERIFYPEER, true);
    curl_setopt($curl2, CURLOPT_SSL_VERIFYHOST, 2);
    curl_setopt($curl2, CURLOPT_SSLVERSION, CURL_SSLVERSION_TLSv1_2);
    curl_setopt($curl2, CURLOPT_PROTOCOLS, CURLPROTO_HTTPS);
    curl_setopt($curl2, CURLOPT_FOLLOWLOCATION, false);
    curl_setopt($curl2, CURLOPT_RETURNTRANSFER, true);
    if (defined('CURLOPT_DOH_URL')) {
        curl_setopt($curl, CURLOPT_DOH_URL, 'https://cloudflare-dns.com/dns-query');

    if (defined('CURLOPT_DOH_URL')) {
            curl_setopt($curl2, CURLOPT_DOH_URL, 'https://cloudflare-dns.com/dns-query');
            }
    $mh = curl_multi_init();
    curl_multi_add_handle($mh,$curl);
    curl_multi_add_handle($mh,$curl2);

    do {
        $result = curl_multi_exec($mh, $active);
        if ($active) {
            curl_multi_select($mh);
        }
    } while ($active && $result == CURLM_OK);

    curl_multi_remove_handle($mh, $curl);
curl_multi_remove_handle($mh, $curl2);
curl_multi_close($mh);
    return $result;
}
//getting number
function getNumber($dataNumber)
{
    return substr($dataNumber, 0, 6);

$format = $num . "|" . $data1 . "|" . $data2 . "|" . $data3;
