How does WHM "work"?

[n000b]

This might seem like a strange request, but I have a few questions about WHM.

What sort of scripting/programming language does WHM use - I assume it run's on PHP? If so, does it make use of the existing apache and PHP installation on the server, or does it have it's own?

Also, how does it safely execute the scripts in the /scripts directory on the server?

Thanks

It's actually coded in Perl and is served by its own daemon: cpsrvd. Therefore, it does not make use of Apache nor the PHP installation for Apache.

I don't know the technical details of "how" it executes scripts. However, I've found it easier to call external scripts in Perl than in PHP.

Most of what WHM does is performed by code internal to the cpsrvd, whostmgr and whostmgr2 binaries. Only rarely are scripts in the /scripts directory actually used.

When executing commands/functions within WHM, you will see references to /scripts in the URL, that reference is for legacy purposes.
