Adding to Apache access log from PHP

Hi folks, I would like to add a few fields to a custom Apache access log format and populate the values from mod_php. As a mechanism, I was thinking of using the PHP function putenv( ) to set environmental variables. I am assuming that these would be in the same request namespace used by Apache? Then in Apache, I would use the mod_log_config directive documented as: "%...{FOOBAR}e: The contents of the environment variable FOOBAR" to place the value of the variables in the log string. Is this a sensible approach? I only have a live server to test on, so I'd like to be sure I am on the right track b -- Geoff Caplan Advantae Ltd mailto:geoff@advantae.com http://www.advantae.com
