#PHP 5.3.4 released with Firebird driver included in the #Windows zip/installer
Php 5.3.4 is released with the firebird driver enabled (for pdo too) but only for the Visual C++ 9 builds
(If you use Apache on Windows you should check if it’s build with VC9 before using the new builds , VC6 build driver is not available for the moment)
ps: apache lounge does have VC9 builds for Apache but i didn’t tested it yet
