[PHP3, Perl and C++ discussion ellided]

Or, use Python for everything.

> Firstly, I use php3 to make web based interface

I use Python over PHP because, like PHP, Ican embed it into the web
server but I can reuse the code in non-web applications so I don't
have to reinvent each wheel.

for data in db.query("select * from users where uid = '%d'" % uid).dictresult():
if crypt(pin, data.pin) == data.pin:
print "PIN of user '%d' is valid" % uid
else:
print "Sorry, you enter incorrect PIN for user '%d'" % uid

I assume that BlueEcho and RedEcho are simply functions that wrap the
strings in font color tags. Such functions can easily be added to Python.
See http://www.druid.net/rides/ for a real example.

I use Python over Perl because I find it to be a cleaner and more logical
language. This is a personal preference thing, of course.

I hardly do anything in C (never cared much for C++ except for a few
specific features) any more as Python gives me the ability to do anything
I could do in C and, if needed, I can always write low level code in C
and link it in.

Check out http://www.python.org/ for more information. For a PostgreSQL
interface for Python see http://www.druid.net/pygresql/ or look in the
PostgreSQL source tree.

As I said, one language for all makes code reuse easier. I find that my
projects generally require web interfaces, CLI interfaces as well as
scheduled background tasks and I can write modules that get imported into
all of them saving me much development time.

Can't argue with that.
