So you should be getting a fresh environment each time. Except I dunno what the Perl stuff is doing to the environment or where you are getting/setting vars in the Perl fixup handler. >are _not_ accessible to apache or mod_perl either at the process level or in the apache table structures. furthermore, phpinfo() does not reflect the normal set of apache CGI-oriented environment variables (SERVER_NAME etc - which are in fact available via getenv), but it does reflect the environment of the shell from which httpd was started (e.g. SHLVL, DISPLAY and such), and it also shows If you run PHP from a shell, that shell is not going to get the Env variables by magic out of the web-server: You'll have to set them in the shell Env for PHP to get them. >the environment variables set by mod_perl during previous transactions handled by the same process. huh? Again: These vars are almost for sure not being set by PHP: Your fixup may be setting them, or you may be keeping the same shell around to run PHP in. PHP gets them from the shell you give it. > I'm not using putenv() at all, and without a php content handler this doesn't happen, but the vars created by the mod_perl fixup handler, which are supposed to expire with the transaction, are persisting within php. does php keep track of environment variables separately from the process environment? if so, where, and how do I get rid of them without knowing their exact names? I would cheerfully settle for detailed documentation too... PHP just rips through all the Env variables in the shell it runs in, and that's what's there. If you're seeing things that don't look right, it almost has to be coming from outside PHP. Disclaimer: I'm just repeating what I've heard on this list before.
