Virtual Host/SuExec/PHP CGI prob

Hello, I have been looking into the possible ways to run php as like a userid as per the perl/suexec method. I have many questions as I am concerned about security foremost. 1) Is running php as a CGI Binary the only possible way to get suexec like security/userid functionality?. 2) Does anyone know what sort of performance drag running php as CGI Binary creates? 3) Problem with testing CGI Binary, without any Suexec stuff involved : On a Development box that already had php4 running, I decided to make the CGI Binary of php. I removed all php module configurations from the httpd.conf and made a test.phtml in my cgi-bin. Gave it o+x permissions.. The script as follows #!/pathtophp/etc/php4/php <? echo "hello"; ?> I have checked the path.. and everything seems to be in order, but i get the following error in my http error logs cgi_main.c(279) : Freeing 0x0813093C (24 bytes), script=- and the script from a web browser returns the error, No input file specified. I have not recompiled apache, if that is important to remove php module stuff?:) I guess it cant find my script file but I dont know why, maybe another configuration option is needed. Any answers to any of these questions would be greatly appreciated. If anyone has succesfully setup suexec&cgi-bin&php-bin running as individual users for different virtual hosts please give me some direction. Thanks Anthony
