What are the benefits of breaking down large PHP scripts into smaller, more manageable components for easier debugging and troubleshooting?

Breaking down large PHP scripts into smaller components makes it easier to isolate and identify issues during debugging and troubleshooting. By organizing code into smaller, more manageable modules, developers can pinpoint specific areas of concern more efficiently. This approach also promotes code reusability and maintainability, as individual components can be easily modified or replaced without affecting the entire script.

// Large PHP script broken down into smaller components

// File: functions.php
function addNumbers($num1, $num2) {
    return $num1 + $num2;
}

// File: main.php
include 'functions.php';

$num1 = 10;
$num2 = 20;

$result = addNumbers($num1, $num2);
echo "The sum of $num1 and $num2 is: $result";
