Re: Converting from PHP4 to php5

Google "php4 to php5 converter" or "php4 to php5 conversion" That should set you on your way. The best way I have read to do this is just run your code on a php5 server and build in php error detection of some kind, then just fix the errors as they come. :) Best, Karl On Jun 3, 2011, at 6:26 AM, Richard Quadling wrote:

i AM WONDERING IF SOMEONE CAN TAKE UP CONVERSION OF MY SOFTWARE FROM PHP4 TO PHP5

Whilst there will be many aspects of the code that will run quite happily, there are several features that have been deprecated and/or removed, depending upon the version of PHP4 and PHP5 you have and want. 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.
