This PHP class lets you perform multiple cURL requests in parallel. Is also provides a max connections per second setting, so you can start multiple parallel requests at different intervals.

For example you want to make 50 requests, which all take 5 seconds, but you only want to start 5 requests per second. The max connections per second setting will start every second 5 new connections, so your total requests take 14 seconds (at t9, the last 5 connections will start).

Requirements

The class is written in PHP5 and uses the curl_multi_init() function.

Usage

A quick example how to use php-mcurl:

$mcurl = Mcurl::factory();
$mcurl->max_per_second = 1;
$mcurl->add_url('http://example.com/foo');
$mcurl->add_url('http://example.com/bar');
$mcurl->execute();
$responses = $mcurl->get_content();
echo $responses[0]['content']; // Print response from first URL

2 URLs are fetched in this example with the first one starting at t0 and the second at t1 (max connections per second = 1)
