There are three problems with your code:

• You're passing a string to post via curl. This is bad. You should prepare carefully the structured data to send.

Example:

 $data = array('appid'=>'12345',
               'query'=>'water bear',
               'results'=>5);
 $data = http_build_query($data, '', '&'); // use native helper methods
 curl_setopt($handle,CURLOPT_POSTFIELDS,$data);

• There is a typo in your code: CURLOPT_POST(FEI)LDS should be CURLOPT_POST(FIE)LDS.

• Yahoo's restful search api url's changing in favor of the BOSS api. Your request uri should look something like this:

http://yboss.yahooapis.com/ysearch/{service,*}?q={keywords}

From the documentation:

BOSS API is an updated service that provides RESTful access to Web, Image, News, Spelling, and Blog search results with a simple pricing scheme based on usage. The service also provides qualifying developer's access to Yahoo! Search Advertising.
