When using php in script that begins with #! it fails as CGI 
but works from the commandline. A simpe script:
#!/usr/local/bin/php
<? echo "Hello\n"; ?>

Running this from the commandline happily prints "Hello".
But when using this as a CGI it gives "No input file 
specified." (the first one in main.c).

I try this on Apache 1.2.6 webserver.

I mainly make most of my cgi scripts this way, partly to avoid 
some of the security issues by putting the main parserbinary 
in the cgi-bin directory.
