Question

I use cURL to send requests to REST API and I would like to add a string to created url befeore execute it. This string is not a parameter.

Do you know how can I do that?

It depends on really what you want to do. If you want to call an URL by appending GET query parameters, you can use string concatenation.

<?php
function get_data($url, $add) {
    $url = $url.$add;
    $ch = curl_init();
    $timeout = 5;
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
    $data = curl_exec($ch);
    curl_close($ch);
    return $data;
}

echo get_data('http://example.com', '?page=mine');
?>

However, if you want to retrieve a specific URL by sending POST query parameters (e.g. to simulate a form being submitted), you need to implement something like this instead.
