There has been lots of talk about web hosts offering and clients needing upgrades to PHP 5. For those of you who might be outside the loop, let me first explain what PHP is. PHP is a framework that works on your hosting server’s side of things. It is a programing language that allows web developers to create content that dynamically interacts with databases.

Now the main reason you would want to upgrade to PHP 5 is that development for PHP 4 ceased at the end of 2007. You will no longer get updates for it, unless they are security related. Critical security updates for PHP 4 will be provided till August 8, 2008. So this is another good reason why a move to PHP 5 might be a good idea.

Where are the advantages of PHP 5 over PHP 4? Well without getting too geeky on you there are a number of improvements that just make it more robust, faster, more secure and easier to work with. What was wrong with PHP 4? Well, nothing really – it is just getting a little long in the tooth. PHP 4 you have to remember was released back in 2000. Think of it as a pair of old shoes you really love. the laces might be lost and your holding the heel on with duct tape but you can still put them on your feet and use them. PHP 5 would be the pair of sneakers you always wanted.

There have also been several public movements to help lead the charge to PHP 5, one of the more popular ones was the GoPHP5.org project that shared information about PHP 5 and kind of helped push a lot of web hosts in the right direction when it came to supporting the most recent stable release of PHP 5.

The name of the game is evolution. As with any technology, we need to move forward as soon as there is a solid stable release because in doing so we can continue to make things bigger, faster, better and stronger.
