Here is the code https://github.com/AYLIEN/aylien_textapi_php/issues/6

<?php

  $ch = curl_init('https://api.aylien.com/api/v1/' . $endpoint);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
  curl_setopt($ch, CURLOPT_HTTPHEADER, array(
    'Accept: application/json',
    'X-AYLIEN-TextAPI-Application-Key: ' . APPLICATION_KEY,
    'X-AYLIEN-TextAPI-Application-ID: '. APPLICATION_ID
  ));
  curl_setopt($ch, CURLOPT_POST, true);
  curl_setopt($ch, CURLOPT_POSTFIELDS, $parameters);
  $response = curl_exec($ch);
  return json_decode($response);
}
echo "<pre>";

$endpoints = array("language", "sentiment", "classify", "hashtags");
$url = "http://www.bbc.com/news/science-environment-27688511";

foreach($endpoints as $endpoint)
  {
