Rules for building FBSQL ------------------------ The fbsql project contains 2 configurations. To build this extension you must first download and install FrontBase. The default instalation path would be c:\usr\FrontBase. If you install it in another location you need to change the include path in the project before compiling. Start Visual Studio, load php_modules.dsw, select the fbsql projects, configuration and build it. Finaly copy php_fbsql.dll to your extension directory and enable it by adding the following line tp php.ini extension=php_fbsql.dll or by calling dl() in each script dl("php_fbsql.dll");
