Yang Zhiyuan, co-founder of Yahoo!, will announce that the company's search network will enter Web services on July 15, March 1. Yahoo! has established the Yahoo Search Developer Network on www.developer.yahoo.com. The company plans to launch this plan at the Search Engine Strategies Conference held in New York. This network will allow developers to create new applications for Yahoo search, including images, videos, news, and regional searches. Members who want to use this service must first go to the http://api.search.yahoo.com/webservices/register_application to apply for a self-idnumber, note: Each idnumber can only search 5000 times a day.

Next, let's take a look at how to use php (as the mainstream development language) scripts to call Yahoo! Search by using the Search API. all scripts are as follows:

// Yahoo Web Services php (as the mainstream development language) Example Code
// Rasmus Lerdorf
// Www.acnow.net

$ Appid = YahooDemo;
// Enter your ID number here

$ Service = array (image => http://api.search.yahoo.com/ImageSearchService/V1/imageSearch,
Http://api.local.yahoo.com/LocalSearchService/V1/localSearch,
News => http://api.search.yahoo.com/NewsSearchService/V1/newsSearch,
Http://api.search.yahoo.com/VideoSearchService/V1/videoSearch,
Web => http://api.search.yahoo.com/WebSearchService/V1/webSearch );
?>
