But a decade has come and gone, and the PHP I liked then is not the PHP in fashion now... My server is running PHP 5.5, but the code is effectively capped at 5.3, and even then uses very little features beyond the basics that PHP 5 added. That is, while other PHP projects I've worked on used things like namespaces (!) and big frameworks (!) like Yii or Symfony, this old blog is just fine with a handful of PHP 5 classes.
So what's got me thinking about a rewrite? I've heard the upgrade from PHP 5 to PHP 7 is relatively painless (my concern without looking at it is that I have to go through the code again to spruce up potential unicode issues, which I last did in 2011...). However even if that's so, and I test it out locally and do the migration work (I don't even have PHP on my gentoo system right now, partly because v5 isn't in mainline portage anymore) then I still have another obstacle: Ubuntu.
