In PHP, how do I reduce arrays with strong typing?

In PHP, reducing arrays can be efficiently accomplished using the `array_reduce` function. This function allows you to iterate through an array while maintaining strong typing by specifying the types of the elements being processed. Below is an example demonstrating how to reduce an array of integers to their sum, while ensuring type safety.

This example showcases how to use the array_reduce function in PHP to sum up an array of integers with strong typing, ensuring that the function behaves as expected.

<?php // Define a typed array of integers $numbers = [1, 2, 3, 4, 5]; // Use array_reduce to sum the elements $sum = array_reduce($numbers, function(int $carry, int $item): int { return $carry + $item; }, 0); echo "The sum is: " . $sum; // Output: The sum is: 15 ?>
