curl_multi_close — Remove all cURL handles from a multi handle
Removes all CurlHandles attached to the CurlMultiHandle, as if curl_multi_remove_handle() was called for each of them.
Prior to PHP 8.0.0 this function also closed the cURL multi handle resource, making it unusable.
No value is returned.
