No input file specified - what does this mean?

Hello to everyone. I want to run PHP4b2 as a CGI, but somehow it's not getting the right environment variables from Apache. When I request a .php file, my php binary gets invoked correctly but it produces the output "No input file specified." I'm running Apache 1.3.6 on FreeBSD, and I added the following to my httpd.conf: ScriptAlias /php/ "/usr/local/bin/" AddType application/x-httpd-php .php Action application/x-httpd-php "/php/php" If I copy my phpv3 binary into /usr/local/bin instead, and then request a .php file, it interprets my script with no problem. Does v4 have a different invocation mechanism due to the security problems experienced with v3? If so, how am I supposed to configure it? thanks for your help ----------------------------------------------- Luke Pond Software Engineer Intelligent Transportation Systems Research Program lukep@its.washington.edu (206) 616-3185
