Implementation Flow - PHP

The complete and detailed implementation flow for this application should look like this:

The web form is first presented to the user. They will enter the root domain URL, for example: http://www.thisistherootdomainurl.com . After that, the user will decide if he or she is interested in the number of back links pointing to the entire domain (home page + inner pages) or only to the specific root domain URL (home page only).

When the form is submitted, PHP will process the user inputs and then establish a connection to the Yahoo API. Details of the request will be sent, for example the Application ID, Requested Domain URL, and additional options (entire domain or to specific URL).

If the application ID is valid, the Yahoo API will send the request back to the server. PHP will receive the request, and then analyze the data by filtering for unique domains. For example, if PHP receive the series of back link URLs seen below:

PHP should filter the back link data to count unique domains. In the above example, there are only five back links coming from unique domains.
