You might get more/better responses if you posted to a web-centric
or PHP centric list.  

The main reason folks I know use PHP is that it is an in-line embedded
scripting language for HTML.  In other words, you PHP code is embedded
in the middle of your HTML.  If you are running an integrated PHP
processor, e.g., mod_php with Apache (as I assume most folks using
Linux would do) then the code is interpreted and run within the context
of the web server.  CGI, whether it is C, Perl, or PHP running as CGI
(most common in a Windows/IIS environment), needs an external process 
to be fired off to interpret or run the application.  This incurs
additional overhead, context switches, and so on.  In the end, with
PHP you can create dynamic pages based upon code embedded in the page
that is interpreted within the context of the web server at run time.

So the question becomes, why do you want to run a CGI model?  There are 
reasons one would choose to do so, but far fewer reasons than there were
years ago in the days before PHP and other embedded scripting languages.
