The end-of-life announcement for PHP 4 has prompted a lot of discussion about whether PHP 5 is worth adopting at all, and even whether or not PHP 5 has hurt PHP as a whole. The technical arguments have been debated (and, alas, that will continue no matter who says what) on the Net for some time now.
What I’m not seeing are the commercial arguments to move to PHP 5 (/me points an accusing finger at the folks from Zend, with whom this discussion has been had before). Businesses will only make the move when there is something to gain from the effort, when the rewards of switching are more than the cost of doing nothing. So let’s see if we can find some reasons to chivvy them along!
Here are the arguments I’ve been making for the last 3 years to pointy-haired bosses that many technical folks ultimately have to answer to. What commercial arguments have you tried in your workplace? Post the good ones that have worked in the comments below, or on the Net on your own blogs for us all to share.
