How do I get twitter posts? - php

Question

I am trying to get twitter posts following this tutorial:
https://www.youtube.com/watch?v=tPrsVKudecs
there aren't a lot of tutorials regarding this online, and twitters console doesn't support running queries anymore as far as I understood.
any idea why this is happening?
This is the output I get in the Chrome "Network":

Any ideas why this is happening?
Is there a better simple way to do it?
EDIT:
tweets_json.php
<?php
require 'tmhOAuth.php'; // Get it from: https://github.com/themattharris/tmhOAuth
// Use the data from http://dev.twitter.com/apps to fill out this info
// notice the slight name difference in the last two items)
$connection = new tmhOAuth(array(
'consumer_key' => '',
'consumer_secret' => '',
'user_token' => '', //access token
'user_secret' => '' //access token secret
));
// set up parameters to pass
$parameters = array();
if ($_GET['count']) {
$parameters['count'] = strip_tags($_GET['count']);
}
if ($_GET['screen_name']) {
$parameters['screen_name'] = strip_tags($_GET['screen_name']);
}
if ($_GET['twitter_path']) { $twitter_path = $_GET['twitter_path']; } else {
$twitter_path = '1.1/statuses/user_timeline.json';
}
$http_code = $connection->request('GET', $connection->url($twitter_path), $parameters );
if ($http_code === 200) { // if everything's good
$response = strip_tags($connection->response['response']);
if ($_GET['callback']) { // if we ask for a jsonp callback function
echo $_GET['callback'],'(', $response,');';
} else {
echo $response;
}
} else {
echo "Error ID: ",$http_code, "<br>\n";
echo "Error: ",$connection->response['error'], "<br>\n";
}
// You may have to download and copy http://curl.haxx.se/ca/cacert.pem
tmhOAuth.php: https://github.com/themattharris/tmhOAuth/blob/master/tmhOAuth.php
and this pem key: http://curl.haxx.se/ca/cacert.pem
All three in the same folder
In the tutorial it should run the query and get the json output.
I get a blank page.
