Array Reduction in PHP

You can reduce an array to a single value using the array_reduce() function, which iteratively reduces the array using a callback function.

Example of Array Reduction

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

// Sum all numbers
$sum = array_reduce($numbers, function($carry, $item) {
    return $carry + $item;
}, 0);
echo $sum . "\n"; // Outputs: 15
?>

Output:

15

Explanation: This example demonstrates how to use array_reduce() to sum all elements in an array.
