Attention guru's!

I build sites with XHTML, CSS, PHP, MySQL and tend to re-use code from previous sites I've built to speed things up.

However, I wonder what tools or trickery you folks use to speed up the process. I'm convinced its the forms in my CMS that slow my production / efficiency down.

Like, I tend to build sites, using one db connection file, two includes(header / footer), take content from the db, use one CSS file, one area for images etc.
But I'm sure I could be doing things a lot quicker.

Also I'm on the look-out for any examples of PHP OOP.
I seem to be creating forms and the validation all the time, when I'm sure I could just re-use 'classes'.

And ways to make my code more 'modular' so I can move it across and re-use it on another site without making too many changes.

Your advice will doubtless be invaluable.


Any help would be fab!
Thanks
