If you’re anything like me, then you may want to see how the previously defined “WebSearchService” class can work under real conditions. Therefore, below I set up a concrete example that shows how the class in question returns 15 different entries associated with the string “Devshed.com” to client code, naturally fetched by the respective Yahoo! Web Search Service.

Here’s the corresponding code sample, along with the pertinent list of results:

try{

// create new instance of 'WebSearchService' class

$ws=new WebSearchService();

// set search query

$ws->setQuery('Devshed.com');

// set number of search results

$ws->setNumResults(15);

// display search results

echo $ws->getSearchResults();

}

catch(Exception $e){

echo $e->getMessage();

exit();

}

// displays the following

See how easy it is to query the Yahoo! Web Search Service using the PHP class that I built before? I guess you do! In this case, this class comes in handy for hiding all the business logic required to implement this specific Yahoo! web service behind its API, and its use demands only a few lines of PHP 5 code.

All in all, I showed you how to use a compact PHP class to query the Yahoo! Web Search Service and eventually return the corresponding results to client code. So, what is the next thing to do now?

Well, due to the flexible nature of the class that you learned before, it’s possible to build a similar one that works with the Yahoo! Video Search Service instead, without having to completely modify its structure. Therefore, in the last section of this tutorial I’m going to show you how to build such a class. But as you might have guessed, to see the details of this process, you’ll have to click on the link below and keep reading.
