why are functions not suitable? you are probably right but I'm interested to understand why.
could you give us an example?

you could tackle this in 2 ways:
1. use eval() to evaluate a string containing php code - define the strings in 1 place.
2. use include()/require() to include a file that contains the relevant code whenever you need
it.
I would use 2. unless you have a technical reason that dictates you must use 1.
eval() is comparitively slow and also has the potential to open up big security holes in
your application (if you want to know why then the http://phpsec.org site is probably a good place to
start reading about security and stuff).
oh and there is also the create_function() function which can be very handy in some circumstances.
