Updating from PHP 5.4 to 5.5 with WHM

November 29, 2015

Hi!

We just updated from PHP 5.4 to 5.5 with WHM. It took the server about 10 minutes to compile, and it went off without any problems. Thanks be to the nerd gods!

We had a worry about a few WordPress installs (WordPress 4.3.1) and an old CodeIgniter codebase – but all went well.

Why the upgrade?

We wanted to take advantage of PHP namespaces. But as an added bonus, we noticed a nice speed boost in PHP – even our old apps are running much zippier now.

… On top of that, apparently PHP 5.5 uses 50% less memory than PHP 5.4.

So far so good.
