Render a set of headlines using PHP

Overview

The sample below shows how to render a set of headlines matching a hard coded search term.

Test it here

Tricky Bits

  • The signature is generated with a query term
  • The signature should be generated with an unencoded query term, but the call itself should take an encoded query term

Exercises for the reader

  • Limit results to a list of your favorite blogs using source filtering
  • Display the headlines using a fancy javascript headline crawler
  • Step through pages of headlines using <limit> and <offset> parameters

# Configure the daylife api server url

	$accesskey = "YOURKEYHERE";
	$sharedsecret = "YOURSHAREDSECRETHERE";


# specify your query

$query = 'Yankee Stadium';

$url_encoded_query = urlencode($query);

# Build your method signature

# For search_X methods, the Core Input is the query term itself
$signature = md5($accesskey . $sharedsecret . $query);

#Draw from news in last 3 days
$end_time = date(U);
$start_time = $end_time - (3 * 86400);

$composed_url = $publicapi_access_url . $method . '?accesskey=' . $accesskey . '&signature=' . $signature . '&query=' . $url_encoded_query;

# kick off the call
$result = file_get_contents($composed_url);

$relatedArticlesResponse = unserialize($result);

$relatedArticles = $relatedArticlesResponse['response']['payload']['article'];
