Twitter bot using Oauth - twitter

Question

I have a twitter bot, where it searches for an #mention and replies to the user depending on what the user says.
It was working fine until this week, when I started getting this error:
Warning: Invalid argument supplied for foreach() in /home/reportax/public_html/reportaxi/twitterbot/config.php on line 14
I stripped down the code to the most basic form, which is the searching for the #mention and then tweeting something when it finds it, but I'm still getting this error. Any ideas?
As I mentioned before, this was working fine until this week, so I know the consumer key, secret, and all that is OK.
here's the code:
<?php
require_once('twitteroauth.php');
define('CONSUMER_KEY', 'MYKEY');
define('CONSUMER_SECRET', 'MYSECRET');
define('ACCESS_TOKEN', 'MYTOKEN');
define('ACCESS_TOKEN_SECRET', 'MYTOKENSECRET');
$twitter = new TwitterOAuth(CONSUMER_KEY, CONSUMER_SECRET, ACCESS_TOKEN, ACCESS_TOKEN_SECRET);
$twitter->host = "http://search.twitter.com/";
$search = $twitter->get('search', array('q' => '#repor_taxi', 'rpp' => 15));
$twitter->host = "https://api.twitter.com/1/";
foreach($search->results as $tweet) {
$status = 'RT #'.$tweet->from_user.' '.$tweet->text;
if(strlen($status) > 140) $status = substr($status, 0, 139);
$twitter->post('statuses/update', array('status' => $status));
}
?
any ideas?

I had the same problem. You need update your code for twitter API 1.1.
<?php
require_once('twitteroauth.php');
define('CONSUMER_KEY', 'MYKEY');
define('CONSUMER_SECRET', 'MYSECRET');
define('ACCESS_TOKEN', 'MYTOKEN');
define('ACCESS_TOKEN_SECRET', 'MYTOKENSECRET');
$twitter = new TwitterOAuth(CONSUMER_KEY, CONSUMER_SECRET, ACCESS_TOKEN, ACCESS_TOKEN_SECRET);
/*The search has change a little bit */
/* Remove this 2 lines */
/* $twitter->host = "http://search.twitter.com/"; */
/* $search = $twitter->get('search', array('q' => '#repor_taxi', 'rpp' => 15)); */
/* Put this new line */
$search = $twitter->get("https://api.twitter.com/1.1/search/tweets.json?q=#repor_taxi&count=15");
/* The Search URL is https://api.twitter.com/1.1/search/tweets.json?q= */
/* Everything after is parameter */
/* You can check parameters list here: https://dev.twitter.com/docs/using-search */
/* Twitter host updated too */
$twitter->host = "https://api.twitter.com/1.1/";
foreach($search as $tweet) {
...
?>
I hope this may help you. Good luck.
