PHP script that queries mysql and writes output to INI

I have an old Win32 application that only accepts import data from Windows INI style files. I have a separate online form that writes data to mysql. I need a PHP application that requires no user interaction. The PHP application must be able to run in a cron tab, query the mysql database, write a file to INI format, and rename the file to an extension '*.BCI' I have test mysql data for you to use and a test file.
