There are, I think, 2 valid approaches to this sort of task. 1 - Get the code base functional with PHP5, but without using any of the new features. This involves handling/converting any code that used deprecated and/or removed features of PHP4. Amongst these, register_globals, magic_quotes and ereg would probably be the most popular to look at. This _SHOULD_ be fairly easy to do. Obviously, the complexity and structure of the current code will dictate the amount of time. If, for example, the code isn't documented and there are no testsuites, then a new developer is only going to be able to handle what the code actually does, and not necessarily what the code is supposed to do. Checking the code's behaviour without a testsuite could be pretty difficult. 2 - Refactor the modules of the application, taking into account new features of PHP5. This could involve moving from PHP4 procedural code to PHP5 OOP. This could require a significant investment in time (and therefore money), depending upon the project. And may not be necessary.
