It's a standard dynamic extension module, so it just needs editing of php.ini (or a file in /etc/php.d), and the module file goes in /usr/lib/php4 (or wherever). Doesn't need to be compiled in to PHP itself. And as a dynamic module, it doesnt need a requireinclude, the functions just become available as if they were built in to PHP. But it does obviously need root privs to install.

Of course if you used the clamscan command line via system(), instead of the module, it would just need that one executable somewhere httpd can find it. Although you'd still want the complete clamav install, for things like freshclam to keep the pattern db updated. Buit that's same-same for f-prot.
