Lorna Mitchell has a new post today with five things that you could gain by upgrading your platform, mostly centered around the changes PHP has made recently.
In recent years, the release cycle of PHP has become much shorter. We now have a much more controlled and well-publicised process of releases, and moving between each version is no longer a leap of faith. The newer versions have HUGE performance improvements, great features, and better security, and the software is free to use. Yet we have a very, very long tail of PHP installations on older versions (around 75% on entirely unsupported versions at this point). Many of the companies I talk to think that upgrading will be pointless and painful, but that's not my experience of migrating PHP projects. Here are a few things you might like to think about or be aware of before you make the decisions that "not broken" is good enough for your applications.
She offers her list of five things, each with a bit of summary and a few links to more information on the topics:
- Improved Performance
- Security and Support
- New Syntax
- Built In Webserver
She also technically includes another in the list (#6 in the top 5, naturally) talking about the password hashing functionality that's been introduced in recent versions and how much simpler it can make your life.
