The first thing to note is that PHP can install three different executables: a CLI (command line interface) executable at /usr/local/bin/php, a CGI (common gateway interface) at /usr/local/bin/php-cgi, and an Apache SO (shared object) at /usr/local/libexec/apache/libphp5.so. So, first question, which of the above files exist? When you run `php -i` in a shell, you are accessing the CLI, most likely (running `which php` should tell you), and IIRC the package doesn't build the Apache SO, so the problem may be in your Apache configuration (is it configured to properly use the CGI executable?), or the complete lack of a CGI in the location shown above. > > If I access phpinfo() with my browser, it > > fails.

This might indicate that you have the CGI *only*. Verify that the Apache daemon user (www? nobody?) has access to the files as mentioned above.

The apache log (maybe /var/log/httpd.error.log?) should have some information, perhaps in addition to what you have seen. I don't know much about running Apache in a jail; you'll need to keep in contact with the list and hope that someone with a clue notices your problem. Since the question is really about PHP instead of FreeBSD, you might try some PHP forums/mail lists as well. Kevin Kinsey -- If Love Were Oil, I'd Be About A Quart Low -- Book title by Lewis Grizzard
