Parsing PHP output

Dear folks, Has anyone ever been able to get a CGI to produce valid PHP output?? Whatever I do, my browser ALWAYS wants to open or save the non-parsed PHP text produced by the CGI file. And yes, I have set the proper ExecCGI and PHP entries in my vhosts.conf; and yes, I restarted the server. Basically, I open an existing php file (in a Perl CGI), and output its contents again to the Apache server. The CGI starts with sending this header: print "Content-type: application/x-httpd-php\n\n"; Then I output the text. But, no matter what I do, it will not parse the PHP code. I do not understand this. Regular PHP files in that dir work fine. There is, as far as I can see, no reason why this should not work. And the PHP file really needs to be generated from the CGI, as it needs to run as a specific user. Anyway, any help would be much appreciated, - Mark
