In what way can using an array instead of a loop improve the functionality of the code?

Using an array instead of a loop can improve the functionality of the code by reducing the number of iterations needed to process data. This can lead to better performance and more efficient code. By storing data in an array, you can easily access and manipulate elements without the need for repetitive loop iterations.

// Using an array instead of a loop to improve functionality
$data = [1, 2, 3, 4, 5];

// Accessing elements in the array
echo $data[0]; // Output: 1

// Modifying elements in the array
$data[2] = 10;

// Printing the modified array
print_r($data); // Output: Array ( [0] => 1 [1] => 2 [2] => 10 [3] => 4 [4] => 5 )
