php中的Slim API POST

I made an API through Slim framework and I was testing it using the Advanced Rest Client. Now I want to implement in my php website the API rest. How Can I do that? Is better use AJAX or PHP for that? Can you give a small code demo?

Thanks in advance, I really appreciate.

I tried this code,is this the best solution: My problem here is that I need to add a header with an authorization key.

$data = array("title" => "otro libro", "isbn" => "998-84-8184-1", "author" => "otro autor :)");
    $ch = curl_init("http://localhost/slimrest/books");
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
    curl_setopt($ch, CURLOPT_POSTFIELDS,http_build_query($data));
    $response = curl_exec($ch);
    curl_close($ch);
    if(!$response) 
    {
        return false;
    }
    else
    {
        var_dump($response);
    }

You want to use AJAX. I guess its popular to use a javascript framework like jquery or angular.

You can then just pass your token along as a part of the body. I am most familar with jquery so heres a link to the docs.
