    Fetching Search Results as Serialized Arrays with Yahoo Web Services and PHP 5 - Next Example
    ( Page 3 of 5 )

    For the sake of clarity and considerations of length, we placed the second example on a new page. Here it is:

    Despite the lengthy source code of the two previous hands-on examples, the truth is that they’re very easy to understand. In the first case, a GET http request is triggered to the corresponding Yahoo! URL in order to use its popular Web Search Service. Note that in the query string I included first the corresponding application ID (which can be obtained by completing a simple registration form), then the search term “Madonna,” and finally the number of results that should be returned to the client.

    Next, the pertinent results are displayed on the browser in XML, wrapped by a pair of <ResultSet></ResultSet> nodes. Very simple to code and read, right?

    And finally, the last example looks very similar to the first one, but in this case, the Video Web Search service is used instead of performing a common search.

    So far, so good. At this time, hopefully you've recalled how to implement the previous Yahoo! Web Search Services directly from some simple PHP 5 scripts. What’s next? Well, as I explained in the beginning of this article, Yahoo! provides web developers with an additional “output” option for specifying in the query string which format the pertinent search result should be returned to the browser.

    If you're working with PHP, this “output” variable must have a value of “php” (output=php), which will cause all of the search results to be returned to the client in the form of a serialized PHP array. As you’ll realize, this feature can help, largely parsing these results using only a few PHP array processing functions, but this topic will be discussed in detail in the section to come.

    So read the next few lines. They’re just one click away
