What are some efficient ways to sum values in an array in PHP without using array_slice?

When summing values in an array in PHP without using array_slice, one efficient way is to loop through the array and accumulate the sum in a variable. By iterating through each element of the array, you can add its value to the sum variable. This method avoids using array_slice and is a straightforward way to calculate the sum of values in an array. 

$array = [1, 2, 3, 4, 5];
$sum = 0;

foreach ($array as $value) {
    $sum += $value;
}

echo $sum; // Output: 15
