I have a PHP script that displays Tweets embedded in a site I built out on my local machine. When I uploaded the site to my IIS 8.0 server, the PHP script no longer works and I receive this error:

Warning: Invalid argument supplied for foreach() in C:\inetpub\wwwroot\i360_new\footer.php on line 76

The script is:

<?php
    ini_set('display_errors', 1);
    require_once('TwitterAPIExchange.php');

    /** Set access tokens here - see: https://dev.twitter.com/apps/ **/
    $settings = array(
        'oauth_access_token' => "xxxxx",
        'oauth_access_token_secret' => "xxxxx",
        'consumer_key' => "xxxxx",
        'consumer_secret' => "xxxxx"
    );


    /** Perform a GET request and echo the response **/
    /** Note: Set the GET field BEFORE calling buildOauth(); **/
    $url = "https://api.twitter.com/1.1/statuses/user_timeline.json";
    $getfield = '?screen_name=interactive360&count=1';
    $requestMethod = 'GET';
    $twitter = new TwitterAPIExchange($settings);
    $string = json_decode($twitter->setGetfield($getfield)
    ->buildOauth($url, $requestMethod)
    ->performRequest(),$assoc = TRUE);
    foreach($string as $items)
        {
            echo $items['text']."<br />";
        }
?>

I thought it might be a PHP version issue but my local machine is running 5.4.10 and my server is running 5.4.14.

Did you compare both servers phpinfo()? While running in almost the same environment each server can work differently depending on which modules are installed.

You might want to make sure that the $string isn't empty. I believe a ForEach will throw this error if you provide a string that is empty. It looks like the string depends on TwitterAPIExchange.php, I see the 'Require Once', but ensure it's configured correctly.

It turns out this was an SSL/CURL issue. In the TwitterAPIExchange.php file, I had to add these two lines to the CURL options array:

CURLOPT_SSL_VERIFYPEER => false,
CURLOPT_SSL_VERIFYHOST => false
