Truncate by Words
Lab: Doing More With PHP String Processing
Video Runtime: 14:35
Truncating or trimming the length of a string down to a set limit is a task that we do often. Right? You have a blog page and you want to show a snippet of the content, but only 200 or 300 words and not the whole 2000 word articles.
WordPress has a function built in that you can use called wp_trim_words(). I have one that I’ve used which is inspired by Laravel and Symfony. It’s part of my Fulcrum plugin that I use on all of my projects. Genesis has one built into too called genesis_truncate_phrase(). There are multiple ways to trim and truncate long strings to a set number of words.
In this episode, let’s explore the one I use and then compare it to wp_trim_words().

Your functions are bloated. Put them on a diet. Think "skinny" and "as few lines as possible."
