I have stores this object in an variable called results. How would i access the profile_image_url for example.

Here is the return value with print_r:

Answer 1

Here are some basic access examples:

//get a single profile url
echo $results->results[0]->profile_image_url;
//or
$tweet = $results->results[0];
echo $tweet->profile_image_url;

//get all the profile urls
foreach($results->results as $tweets){
  echo $tweet->profile_image_url;
}

Of course the same basic concept applies to all the other properties, except (for this specific example data) the metadata property, which is an object.

//to get result type
echo $results->results[0]->metadata->result_type;
