// Define the options you use to call the api

// Pull the data from the webpage;
// http_build_query = http://php.net/http_build_query
// file_get_contents = http://php.net/manual/en/function.file-get-contents.php
// Allows us to easily merge the keys and the values of the array declared above
$encoded_json_output = file_get_contents($api_base_url . '?' . http_build_query($api_get_options,"","&"));

// Decode the returned json data with the built in PHP function

// We use the value TRUE as second parameter to turn it into a proper array

// Loop through the decoded json (which is now an assoc array)

    // You can make a table, divs, whatever to display. As an example I'm just going to output a few basic items in the API.
