The extensions to PHP that allow things like database access are also written in C. As I understand it, writing custom PHP libraries that use C code is a very popular practice among high-volume sites.

Yes, but the difference is that if a user has permission to run mod_perl as part of a shared server environment that user can load leaky C code - custom C modules for php would have to be compiled into the server by the administrator.

I don't think that mod_perl's API for accessing apache data is inherently more dangerous than the PHP equivalent. They both give you access to the same information about the request.

Mod_perl can modify apache internals - that's why it's so powerful. You can do anything with mod_perl that you could do with a C module (making it great for prototyping apache C modules). The only things PHP can modify are selected PHP settings and the server output.
