I don't know how many times people have asked me to build a upload progress indicator into a website, or CMS, which until now has not been possible with PHP.

I recently came across this article (via PHPDeveloper) about how to build an upload progress bar in PHP 5.2!

I know there are plenty of other reasons to upgrade to PHP5, but this is a reason that the client will understand and want to act on.

The upgrade cycle to PHP5 hasn't progressed too quickly, probably a case of if it aint broke -- don't fix it, perhaps features like this that people have been craving will make things move a long a little quicker.
