PHP Higher Order Functions - Array Filter

In this video I go through how to filter through arrays using array_filter in PHP.

Array Filtering is something I do on a near daily basis with the various applications I personally build. array_filter works with a number of different data types including arrays with Objects.

Let me know if you have any questions below in the comments.
