Is there a simple way to write a common function for each of the CRUD (create, retreive, update, delete) operations in PHP WITHOUT using any framew
Of course not, that's why those frameworks exist and implement crud facilities. I'd first try to convince whomever it takes to actually use an existing framework and second, failing the above, I'd take a look at one or two of them and copy the implementation ideas. Failing all that you could take a look at http://www.phpobjectgenerator.com/
