Zend_Service_Twitter_Search provides a client for the Twitter Search API. The Twitter Search service is use to search Twitter. Currently it only returns data in Atom or JSON format but a full REST service is in the future which will support XML responses. Returns the top ten queries that are currently trending on Twitter. The response includes the time of the request, the name of each trending topic, and the url to the Twitter Search results page for that topic. Currently the search API for trends only supports a JSON return so the function returns an array. trends(); foreach($twitter_trends as $trend) { print $trend['name'] . ' - ' . $trend['url'] . PHP_EOL } ]]> The return array has two values in it: name, the name of trend. url, the url to see the tweets for that trend. Using the search method returns tweets that match a specific query. There are a number of Search Operators that you can use to query with. The search method can accept six different optional URL parameters passed in as an array: lang, restricts the tweets to a given language, lang must be given by an ISO 639-1 code. rpp, the number of tweets to return per page, up to a max of 100. page, the page number to return, up to a max of roughly 1500 results (based on rpp * page) since_id, returns tweets with status ids greater than the given id. show_user, when "true", adds ">user<:" to the beginning of the tweet. This is useful for readers that do not display Atom's author field. The default is "false" geocode, returns tweets by users located within a given radius of the given latitude/longitude, where the user's location is taken from their Twitter profile. The parameter value is specified by "latitude,longitude,radius", where radius units must be specified as either "mi" (miles) or "km" (kilometers). The following code sample will return an array with the values search results search('zend', array('lang' => 'en')); ]]> The following code sample will return a Zend_Feed_Atom object. search('zend', array('lang' => 'en')); ]]> While the Twitter Search API only specifies two methods, Zend_Service_Twitter_Search has additional accessors that may be used for modifying internal properties. getResponseType() and setResponseType() allow you to retrieve and modify the response type of the search between JSON and ATOM.
