How can the array_reduce() function be utilized to sum values in PHP without using a foreach loop?

To sum values in PHP without using a foreach loop, you can utilize the array_reduce() function. This function iterates over an array and applies a callback function to each element, accumulating a final result. By providing a callback function that adds each element to the accumulator, you can easily sum up the values in the array without the need for a foreach loop. 

$array = [1, 2, 3, 4, 5];

$sum = array_reduce($array, function($carry, $item) {
    return $carry + $item;
}, 0);

echo $sum; // Output: 15
