美国东部时间3月1日，雅虎公司联合创始人之一的杨致远将宣布公司的搜索网络将进入web服务。雅虎公司在www.developer.yahoo.com网站建立了yahoo search developer network，公司计划在此纽约举行的搜索引擎战略大会(search engine strategies conference)上推出这一计划。该网络将允许开发者在雅虎搜索之上建立新的应用程序，其中包括图像、视频、新闻以及地区搜索等内容。想要使用这项服务的会员必须先去http://api.search.yahoo.com/webservices/register_application 申请一个自已的id号，注：每个id号每天只能搜索5000次。
下面我们看一下，如何用php脚本调用yahoo! search api实现搜索的效果，全部脚本如下：
'http://api.search.yahoo.com/imagesearchservice/v1/imagesearch',
'local'=>'http://api.local.yahoo.com/localsearchservice/v1/localsearch',
'news'=>'http://api.search.yahoo.com/newssearchservice/v1/newssearch',
'video'=>'http://api.search.yahoo.com/videosearchservice/v1/videosearch',
'web'=>'http://api.search.yahoo.com/websearchservice/v1/websearch');
?>
