Retrieving menu information from mmjmenu api to deliver to my website - php

Question

I am new to working with api and have been searching for the little tiny piece of code that makes the following snippit possible, but I am having trouble finding it. I have been watching tutorials on jquery, ajax, json, and php but have not found exactly what I need. If someone could show me a simple example of how the request would be constructed from the opening tag of the file to the closing tag it would be very helpful. After I get the data returned I can figure out how to parse and style it for display.
The first piece of code is the example that someone else said they use but I tried it (with my own api key) and I seem to be missing something. The second code is the "Mmjmenu.php" file that I assume needs to be in the same directory as the first php file. Following the code is the error I get.
("my api key" is replacing my actual key)
<?php
require 'API/Mmjmenu.php';
$client = new Mmjmenu('my api key');
$menuItems = $client->menuItems();
$menuItems = json_decode($menuItems, true);
foreach($menuItems['menu_items'] as $item)
{
echo $item['name'];
}
?>
This is the "Mmjmenu.php" file (can be found on git hub):
<?php
class Mmjmenu {
private $domain = 'https://mmjmenu.com/api/v1';
private $active_api_key;
private $active_domain;
private $username;
private $password;
public function __construct($api_key, $active_domain = null, $active_api_key = null) {
$this->setActiveDomain($this->domain, $api_key);
}
public function setActiveDomain($active_domain, $active_api_key) {
$this->active_domain = $active_domain;
$this->active_api_key = $active_api_key;
$this->username = $this->active_api_key;
$this->password = 'x';
}
private function sendRequest($uri, $method = 'GET', $data = '') {
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://mmjmenu.com/api/v1" . $uri);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, false);
curl_setopt($ch, CURLOPT_MAXREDIRS, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Content-Type: application/json',
'Accept: application/json'
));
curl_setopt($ch, CURLOPT_USERPWD, $this->username . ':' . $this->password);
$method = strtoupper($method);
if($method == 'POST')
{
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
}
else if ($method == 'PUT')
{
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'PUT');
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
}
else if($method != 'GET')
{
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, $method);
}
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 10);
curl_setopt($ch, CURLOPT_TIMEOUT, 30);
$result = new StdClass();
$result->response = curl_exec($ch);
$result->code = curl_getinfo($ch, CURLINFO_HTTP_CODE);
$result->meta = curl_getinfo($ch);
$curl_error = ($result->code > 0 ? null : curl_error($ch) . ' (' . curl_errno($ch) . ')');
curl_close($ch);
if ($curl_error) {
//print('ERROR');
}
return $result;
}
/****************************************************

public function menuItems() {
$base_url = '/menu_items';

public function menuItem($id) {

$menuItem = $this->sendRequest($base_url);
return $menuItem->response;
}
}
?>
This is the error I get when executing the first file:
Fatal error: Class 'Mmjmenu' not found in /home/...(my directory).../mmtest.php on line 4
