I'm still fighting a losing battle in my attempts to get PHP speak to mysqli. I can access MySql via the prompt. Apache and PHP are installed and working. In Apache's config file PHPIniDir is set to "C:\php", which is where I unzipped the binary download files, and set LoadModule php5_module C:\php\php5apache2_2.dll. In php.ini I have uncommented the mysql.dll and mysqli.dll extensions and set extension_dir = "C:\php\ext\". I have edited the environment variables to include C:\php and C:php\ext. I am running Vista Home Premium 32 bit with SP2, Apache 2.2, PHP 5.3.3 and MySql Server 5.1. What have I missed?
