Parametri

mh

option

One of the CURLMOPT_* constants.

value

The value to be set on option.

value should be an int for the following values of the option parameter:

Option Set value to
CURLMOPT_PIPELINING Pass 1 to enable or 0 to disable. Enabling pipelining on a multi handle will make it attempt to perform HTTP Pipelining as far as possible for transfers using this handle. This means that if you add a second request that can use an already existing connection, the second request will be "piped" on the same connection. As of cURL 7.43.0 you can also pass 2 to try to multiplex the new transfer over an existing HTTP/2 connection if possible. Instead of integer literals, you can also use the CURLPIPE_* constants if available.
CURLMOPT_MAXCONNECTS Pass a number that will be used as the maximum amount of simultaneously open connections that libcurl may cache. By default the size will be enlarged to fit four times the number of handles added via curl_multi_add_handle(). When the cache is full, curl closes the oldest one in the cache to prevent the number of open connections from increasing.
CURLMOPT_CHUNK_LENGTH_PENALTY_SIZE Pass a number that specifies the chunk length threshold for pipelining in bytes.
CURLMOPT_CONTENT_LENGTH_PENALTY_SIZE Pass a number that specifies the size threshold for pipelining penalty in bytes.
CURLMOPT_MAX_HOST_CONNECTIONS Pass a number that specifies the maximum number of connections to a single host.
CURLMOPT_MAX_PIPELINE_LENGTH Pass a number that specifies the maximum number of requests in a pipeline.
CURLMOPT_MAX_TOTAL_CONNECTIONS Pass a number that specifies the maximum number of simultaneously open connections.

If you want to enable both HTTP/1.1 pipelining and HTTP/2 multiplexing...

<?php
curl_multi_setopt
($mh, CURLMOPT_PIPELINING, 3);
?>

or

<?php
curl_multi_setopt
($mh, CURLMOPT_PIPELINING, CURLPIPE_HTTP1 | CURLPIPE_MULTIPLEX);
?>
