In PHP, how do I filter arrays for production systems?

In PHP, filtering arrays is a crucial operation for production systems. The `array_filter` function can be used effectively to filter the elements of an array using a callback function. This allows you to keep only the elements that meet specific criteria.

Here's an example of how to filter an array:

2 [3] => 4 [5] => 6 [7] => 8 [9] => 10 ) ?>
