According to this new article from Application Development Trends today, a collaboration has been formed between FileMaker users familiar with PHP and Zend to create a new kind of API to the FileMaker system.
FileMaker's senior product manager Kevin Nathanson says that FileMaker is addressing two audiences with the API beta: existing users of the company's database software, and PHP developers looking for simpler database software than DBMSs such as MySQL.
In fact, developers have been interested in connecting this everyman database software with the popular embedded scripting language for some time, and FileMaker's PHP API has a predecessor: FX.php, an independently developed, open-source PHP class designed to pull data from FileMaker Pro using the XML output by Server Advanced for FileMaker 7 or the Web Companion for FileMaker 5 and 6.
Developers are reminded that the library is still in a beta format and that constant work is being done to enhance its functionality. You can get complete information about the library here.
