The support for the original firebird and interbase test has been somewhat ignored over the years, and my own situation did not help my own support for it. Currently I am going through a heavy piece of work bringing all the web services stack up to date. Using the original ibtest.php as a basis to check out just where we are with the current PHP drivers. Today I am close to having a working version of ibtest.php for all three of the current drivers, but I need to move the live web services stack to the current builds of PHP and Firebird.
The next step is to extend the list of tests to action some of the newer facilities provided by both Firebird and the PHP drivers, which may depend on just which is being used.
Overview of where I am today ... so much for a relaxed retirement.
