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);
?>
