PHP5 Breaking Software

[DaveLite]

I have been testing some software that I was willing to buy until I read about PHP5. I still want the software, but I want it to last longer than the time it will take for my webhost to install PHP5 on the servers and break my site. My host says that the upgrade to PHP5 will be done as soon as possible.

The software company says the Basic Package requires PHP4+. The source code edition will run on PHP5. Does this maybe have something to do with the Zend Optimizer?

Why would I need the developers edition (Source Code Edtion) of this software? I have no problem configuring software but I"m not a developer or a coder.

I'm looking for answers to the above questions, PLUS any option that might cross your mind.

well, if you really need to test in a php5 environment you could install apache/php5 on your local machine and test it out.

One misunderstanding I see is all php is is a set of scripts. Very seldom do you find compiled programs. Well you do with the whole zend thing but they aren't really compiled in the true sense of the word.

A source code edition for all things php is the best way to get them if there is a choice. It makes it much easier to fix things, or have someone else do it, later on. ;)
