Socket programming with PHP risky?

I've noticed in the PHP docs "EXPERIMENTAL" is marked over all the
socket functions. Would it be risky to develop a PHP socket app using
those functions? It seems they could change with the next release and
my app would instantly stop working.

On the other hand, I've found a lot of tutorials extolling PHP's socket
functions, and since I know PHP a bit now I would rather use it for my
TCP socket application than learn C and implement it there.

What do you think?
