I want to progam a library module in C (or C++). I then want to call this module from a PHP program running on Apache.

Does Linux have anything akin to Windows DLL (Dynamically-Linked Library)? If so what are they called? Can they be called from PHP at runtime? If so, can you pass parameters to them?

I do not even know if you can call a DLL from PHP on Windows (I am a PHP newbie) so I may be jumping the gun asking these questions in the first place, but any advice is appreciated, no matter how partial or indirect.

Thanks!

Dynamically linked libraries are nothing new nor special. The concept with terminal sytems dates back to the late 60's. It is not a Windows concept.
It really picked up steam with programmers in the 80s with OOPs like SmallTalk and later C++.

Anyway,, all it is basically is a shared or remote library that is not placed in the executable at compiled time but simply a seperate library called upon as needed.

For an example, the GNU/Linux world, look no further then your /lib or usr/lib directories and files named like libxxx.so or libxxx.a with versions and revision numbers like so..
libxxx.so.1.2 ..

In the Window's world you have libraries both static (*.lib) and dynamic (*.dll)

Both of your posts are helpful. I will take a look at the suggested books as well.
