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 ($twitterTrends as $trend) { print $trend['name'] . ' - ' . $trend['url'] . PHP_EOL } ]]> The return array has two values in it: name is the name of trend. url is 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 is the number of tweets to return per page, up to a maximum of 100. page specifies the page number to return, up to a maximum of roughly 1500 results (based on rpp * page). since_id returns tweets with status IDs greater than the given ID. show_user specifies whether to add ">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 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 methods that may be used for retrieving and modifying internal properties. getResponseType() and setResponseType() allow you to retrieve and modify the response type of the search between JSON and Atom.
