One of examples, how to make multi_curl faster twice (pseudocode) using Fibers:

<?php

$curlHandles
= [];
$urls = [
'https://example.com/1',
'https://example.com/2',
...
'https://example.com/1000',
];
$mh = curl_multi_init();
$mh_fiber = curl_multi_init();

$halfOfList = floor(count($urls) / 2);
foreach (
$urls as $index => $url) {
$ch = curl_init($url);
$curlHandles[] = $ch;

// half of urls will be run in background in fiber
$index > $halfOfList ? curl_multi_add_handle($mh_fiber, $ch) : curl_multi_add_handle($mh, $ch);
}

$fiber = new Fiber(function (CurlMultiHandle $mh) {
$still_running = null;
do {
curl_multi_exec($mh, $still_running);
Fiber::suspend();
} while (
$still_running);
});

// run curl multi exec in background while fiber is in suspend status
$fiber->start($mh_fiber);

$still_running = null;
do {
$status = curl_multi_exec($mh, $still_running);
} while (
$still_running);

do {
/**
* at this moment curl in fiber already finished (maybe)
* so we must refresh $still_running variable with one more cycle "do while" in fiber
**/
$status_fiber = $fiber->resume();
} while (!
$fiber->isTerminated());

foreach (
$curlHandles as $index => $ch) {
$index > $halfOfList ? curl_multi_remove_handle($mh_fiber, $ch) : curl_multi_remove_handle($mh, $ch);
}
curl_multi_close($mh);
curl_multi_close($mh_fiber);
?>
