Updated: 05/07/16 Now Supports Facebook and Twitter.
This class uses the twitter API class that user, J7mbo has created. https://github.com/J7mbo/twitter-api-php
The class starts by pulling the users twitter information. After taking that information it takes the user name and full name of the user you originally looked up and goes through facebook to find the person. Afterwards using the facebook and twitter information, we now look for the instagram infromation.
$newSearch = new search;
$getInformation = $newSearch("nasa"); // The name of the user you want to search goes inside the quotes.
var_dump($getInformation); // view the results that the class has returned.
Noted Problems Still some results are incorrect with facebook. Since sometimes the user's name is actually their username the API does not pull it. Working on a version that doesn't require the Twitter API class via J7mbo.
