Hello, I would like to make an API that will execute a command within my MIKROTIK

Hi, I would like to create an API that executes a command within the mikrotik, which is not how the php file would be to directly send the command to the mikrotik that I can not find by any side this / ip dhcp-client release 0. This api that I show when I run it from the web server appears an error.

<?php

require('routeros_api.class.php');

$API = new routeros_api();

$API->debug = true;

if ($API->connect('192.168.17.135', 'api', 'api')) {

    $API->write('/system/script/run',false);
    $API->write("=.id=script5");


   $API->disconnect();

}

?> 

The error would be this:

  

Warning: require (routeros_api.class.php) [function.require]: failed to   open stream: No such file or directory in   D: \ usbwebserver \ root \ api \ routeros_api.php on line 3

     

Fatal error: require () [function.require]: Failed opening required   'routeros_api.class.php' (include_path = '; C: \ php5 \ pear') in   D: \ usbwebserver \ root \ api \ routeros_api.php on line 3.

Please, if someone could help me.
