I am new to PHP and I’m trying to amend code from the tutorial “Build Your First Twitter App Using PHP in 8 Easy Steps” to use the Twitter search API rather than the status. Previous iteration using

echo "<pre>";
print_r($string);
echo "</pre>";

to display my results worked great. However, I’m trying to adapt it to use the $foreach function used in the tutorial, but it only returns the headings. Here is the full code (minus the access tokens)

<?php

require_once('TwitterAPIExchange.php');

/** Add a title.  Specify Twitter API to be used. We are using search. Then specify fields and requestMethod, bring back 5 most popular**/
echo "<h2>Top 5 Tweets for Cloud Computing</h2>";
$url = 'https://api.twitter.com/1.1/search/tweets.json';
$getfield = '?q=Cloud Computing&count=5&result_type=popular';
$requestMethod = 'GET';

/** Connect to the Twitter API**/
$twitter = new TwitterAPIExchange($settings);
$string = json_decode($twitter->setGetfield($getfield)
->buildOauth($url, $requestMethod)
->performRequest(),$assoc = TRUE);
if($string["errors"][0]["message"] != "") {echo "<h3>Sorry, there was a problem.</h3><p>Twitter returned the following error message:</p><p><em>".$string[errors][0]["message"]."</em></p>";exit();}

/* echo "<pre>";
print_r($string);
echo "</pre>"; */

foreach($string as $items)
     {
        echo "Time and Date of Tweet: ".$items['created_at']."<br />";
        echo "Tweet: ". $items['text']."<br />";
        echo "Tweeted by: ". $items['user']['name']."<br />";
        echo "Screen name: ". $items['user']['screen_name']."<br />";
        echo "Friends: ". $items['user']['friends_count']."<br /><hr />";
    }
?>

Any help would be greatly appreciated. Thanks in advance.

maybe try in your foreach loop this
```
foreach($string as $items => $value)
```

The data that you want appears to be one level further into the array than you are currently going. Specifically, the data is within a statuses sub-array. You simply need to run your foreach at that level instead of the top level.
```
foreach($string['statuses'] as $items)
 {
 echo "Time and Date of Tweet: ".$items['created_at']." ";
 echo "Tweet: ". $items['text']." ";
 echo "Tweeted by: ". $items['user']['name']." ";
 echo "Screen name: ". $items['user']['screen_name']." ";
 echo "Friends: ". $items['user']['friends_count']." <hr />";
}
```
