A convenience wrapper around curl_multi_await

namespace HH\Asio;

function curl_exec(
  mixed $url_or_handle,
): Awaitable<string>;

Pass a cURL handle, or, more simply, a string containing a URL (and the cURL handle will be created for you), and the cURL request will be executed via async and the string result will be returned.

curl_multi_info_read must be used to retrieve error information, curl_errno can't be used as this function is a wrapper to curl_multi_await.



  • mixed $url_or_handle



The following shows a scenario where you are going to wait for and return the result of cURL activity on URLs, using the convenient wrapper that is curl_exec.

async function get_curl_content(Set<string> $urls): Awaitable<Vector<string>> {
  $content = Vector {};
  foreach ($urls as $url) {
    $str = await \HH\Asio\curl_exec($url);
    $content[] = \substr($str, 0, 10);
  return $content;

async function run(): Awaitable<void> {
  $urls = Set {
  $content = await get_curl_content($urls);
