Re: How to call PHP as standalone from a CGI perl program?

I figured it out. The problem is that php3 when called from a CGI perl program thinks that it's a CGI program itself, even though the intention is to run it standalone. That's why its behavior was different than when called from the command line. Clearing out the following environment variables in Perl before calling php3 solves the problem: delete $ENV{"SERVER_SOFTWARE"}; delete $ENV{'SERVER_NAME'}; delete $ENV{'GATEWAY_INTERFACE'}; delete $ENV{'REQUEST_METHOD'}; > ----- Original Message ----- > From: Steve Hsieh <steveh@eecs.umich.edu> > To: <php-general@lists.php.net> > Sent: Friday, July 07, 2000 8:32 PM > Subject: [PHP] How to call PHP as standalone from a CGI perl program? > > > Hi all, > > I am have some Perl-based CGI scripts that I'd like to use.
