Hello Everyone, I am a web designer and I am trying to convince my job to upgrade their servers from php 4 to php 5. Mostly so I can make use of the better object oriented functionalities. This company has alot of websites on this server and they never tried to upgrade cause they are afraid that some websites that implement php 4 wont work with php 5.
My Question Is.
For a server that has alot of websites with php 4 on it. How big of a risk is it to upgrade to PHP 5 ???
