I think you can test for the availability of an extension, but I don't know how. I'm sure someone will be able to tell us. To enable your script to use one or the other, you could wrap each database call in your own "mysqldave()", which would check the mysqli availability and call the appropriate API. You'd obviously check the mysqli availability at startup, then store the status somewhere for your wrapper to query. /Per Jessen, Zürich -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
