In the long run, if it was run thousands of times in a single page load, the first example will perform slightly better than the second. The WP filter system and calling many functions takes a bit more time than calling one function. However, while I don’t have any way to test this, I suspect that the time involved would be measured in microseconds. Like I said, you’d need to have thousands of functions/filters to really make a difference. If you prefer one function over many than that’s the way you should go. For me it would be a matter of what will be easier for me to figure out when I look at it in a year because I need to change something.

ACF wouldn’t be so widely used in WordPress if it didn’t have some pretty amazing capabilities. In this article, we look at a few of the features we’ll discuss during “7 things you didn’t know you could do with ACF” at #WPEDecode later this month. https://t.co/5lnsTxp81j pic.twitter.com/Yf0ThPG1QG— Advanced Custom Fields (@wp_acf) March 16, 2023
