Does using functions in PHP consume more memory compared to using include?

Using functions in PHP does consume more memory compared to using include because functions require additional memory to store their code and variables. However, functions provide modularity and reusability, making the code more organized and easier to maintain. If memory consumption is a concern, consider balancing the use of functions with includes to optimize performance. 

<?php
// Using include to include external files
include 'helper_functions.php';

// Using functions for modularity and reusability
function calculate_sum($a, $b) {
    return $a + $b;
}
