The Gravity Forms Add-on Framework makes the job of creating an add-on really easy. But there’s a couple of problems with letting it load our text domain for us:
PHP has some handy Date classes, including one for specifying date intervals. But you need to be wary of some idiosyncrasies, as I just found out.
Sometimes the WooCommerce out of stock message isn’t quite appropriate. Here’s a couple of ways to change that message.
Ever needed to search for a post by something other than the title or post content? If you’ve built a website with custom post types that have additional fields, it’s a good chance that admins will need to search on your custom meta.
Customising the AJAX output of WordPress plugins can often be a breeze, when the authors oblige other developers by peppering their code with action and filter hooks. But if they don’t, you can always fall back on hacking the plugin’s AJAX action.

I’ve heard many times that PHP doesn’t really do Unicode, or not properly.

WordPress likes to move pagination into the pretty URL and out of query parameters.
