you need to use json_decode : http://php.net/manual/en/function.json-decode.php
<?php
error_reporting(E_ALL);
ini_set("display_errors", 1);
require_once('TwitterAPIExchange.php');
$settings = array(
'oauth_access_token' => "xxx",
'oauth_access_token_secret' => "xxx",
'consumer_key' => "xxx",
'consumer_secret' => "xxx"
);
$url = "https://api.twitter.com/1.1/search/tweets.json";
$requestMethod = "GET";
$getfield = '?q=cloud%20computing&count=5&result_type=popular';
$twitter = new TwitterAPIExchange($settings);
$response = $twitter->setGetfield($getfield)
->buildOauth($url, $requestMethod)
->performRequest();
$string = json_decode($response, true); // there you handle twitter response
print_r($string); // here is the echo'd result, not needed after
// from here, you have access to the data
// then, a foreach loop will give you access to whatever you want to echo
foreach($string['statuses'] as $tweets) {
$tweet = $tweets['text'];
echo "<p>Tweet: $tweet </p>";
}
?>
updated with the loop example
