php classes

[drag0n]

Hi:
I am about to start on a small php project consisting of maybe a total of 10-15 php scripts and less then 10 html pages.
I have always programmed php using functions and rarely used template engines. Since my last php project (about a year ago); i have gained knowledge in c++ and java; so I was thinking I should test out oop in php for this project.
since this is a small-sized project; is it worth the trouble to use a template engine and oop? or should I wait for larger project to test oop in php?
as for many of the php classes i see out there (smtp,authentication,mysql,forms,ajax,etc...); if I need all of those functions; would it be easier to just create simple functions myself for these tasks since this is a small project? it seems as if it would be more trouble to learn the syntax of each class then to write a function or even class of my own.
since i have been away from php/web programming for a long time; maybe I can get some input from you guys.
classes or functions for a small website?
write my own classes for simple functions (ie: database,smtp,forms) or use other people's classes and learn their syntax...?

thanks in advanced.

You can use OOP without necessarily using a template engine.

On smaller projects, I often find myself using a hybrid of classes for the business layer and procedural code for the basic structure of the individual pages.

And what about using other people's classes?
Do you usually develop your own for small projects or use all other peoples?

Noone can say use classes or write your own.

I'm using classes in some parts of projects. Because to write is again is costing me waste of time.

And I'm writing my code in some parts. Because to learn a class will costing me waste of time.

My think sequence is like this :

1. I need to do smth.
2. Search if it's done before
3. If it's done before check out if it fit needs
4. Consider to rewrite or modify it which is quicker or solid
5. Never forget KISS rule
6. Do it.
