1. Install the required build-tools (some might already be installed on your system).

We want to upload file to a server with POST HTTP request. We will use curl functions.

// data fields for POST request
$fields = array("f1"=>"value1", "another_field2"=>"anothervalue");

// files to upload
$filenames = array("/tmp/1.jpg", "/tmp/2.png");
