CURRENT APIs & WEB SERVICES

“We have created a StrikeIron API in Zend Framework because of its Web services consumption capabilities and the momentum it is experiencing as a platform for developing Web applications. This makes it extremely easy for PHP developers to access multiple StrikeIron services in a consistent way, greatly extending the capabilities of Web apps that utilize Zend Framework.”
