When ServerName in httpd.conf is set differently then the actual host's name, the return values of anything called with system, exec, and passthru (except for running the "/bin/date") is always -1.  For instance, we have a machine named phony.wwc.edu, but in apache we set the ServerName to hotnest.wwc.edu.  Suddenly doing something like  system("echo blah",$errno); print $errno; prints -1 instead of 0.  This is completely unrelated to safe mode, btw. (which was our first suspect)

why would you want to put a bogus hostname in your
ServerName directive?

It's called "virtual hosting", and we really should
fix this if it is an acutal bug.

Thank you for taking the time to report a problem with PHP.
Unfortunately, PHP 3 is no longer supported. Please download
the latest version of PHP 4 from http://www.php.net/downloads.php

If you are able to reproduce the bug with one of the latest
versions of PHP, please change the PHP version on this bug report
to the version you tested and change the status back to "Open".
Again, thank you for your continued support of PHP.
