HomePHP Page 2 - Count Backlinks from Unique Domains Using Yahoo Inbound Links API
Requirements - PHP
If you've just started using the Yahoo Site Explorer Inbound Links API and want to know how far you can take it, keep reading. This three-part series will show you how to build an application that can help you track your links.
This web application is written in PHP and should run in an Apache/Linux/MySQL web environment (MySQL database is not needed for this implementation, although it can be integrated). Paid hosting enables important PHP functions which are needed to run this application, for example file_get_contents. You need to consult with your hosting provider to find out if there are limitations on the PHP functions you can use, such as the example function provided earlier.
Remember that if you are in a limited hosting environment -- as you would be with free web hosting, for example -- there is no way you can run this type of application. Web hosting companies offering free hosting services typically disable these PHP functions (used for grabbing data from outside the domain, like API) to control spam and abuse.
However, you can run the application perfectly inside your own XAMPP local host (to be used just for your own consumption). If you use either Windows or Linux, you can install XAMPP (it is bundled with Apache, MySQL and PHP) which you can use to run this application. If you are interested in using XAMPP, you can read the tutorial at the link, as well as this one.
Other than that, assuming you have read the two introductory articles on the Yahoo Inbound Links API (provided in the first section), you should have your own Yahoo Application ID which is needed for this application.
