mod_php or php-fast_cgi?

[unilasys]

I'm building a test server. The client would want a PHP Perl combo. PHP as the primary scripting language, to interface with legacy PERL apps which they developed in-house several years ago (it would seem that they are not yet ready to transition those apps and adopt the current technologies, AJAX, RoR, Python, etc.).

To use PHP and Perl side by side, will fast_cgi do the trick? or use mod_php and mod_perl?

The in-house developer is very much concern with security and thus he will not let anyone touch the server's legacy Apache 1.3 through these mods except for fast_cgi. But if I can find a good argument to convince him otherwise, I might do so.

Tell me what you think!

Unless you need the Apache functions in PHP or Apache API in Perl, it's not worth the battle; use FastCGI. If it turns out later you need either, you can switch.
