Array Filtering in PHP

You can filter arrays using the array_filter() function, which allows you to filter elements based on a callback function.

Example of Array Filtering

<?php
$numbers = array(1, 2, 3, 4, 5);

// Filter even numbers
$even_numbers = array_filter($numbers, function($number) {
    return $number % 2 == 0;
});
print_r($even_numbers);
?>

Output:

Array
(
    [1] => 2
    [3] => 4
)

Explanation: This example demonstrates how to filter an array using array_filter() to get only even numbers.
