In what ways can separating PHP code into distinct blocks or functions improve code readability and maintainability in a project like this?

Separating PHP code into distinct blocks or functions can improve code readability and maintainability by breaking down the code into smaller, more manageable parts. This makes it easier to understand the logic of the code, locate and fix bugs, and make future updates or modifications. Additionally, using functions allows for code reusability, reducing redundancy and promoting a more organized and structured codebase.

// Example of separating PHP code into functions for improved readability and maintainability

// Function to calculate the area of a rectangle
function calculateRectangleArea($length, $width) {
    return $length * $width;
}

// Function to display the result
function displayResult($area) {
    echo "The area of the rectangle is: " . $area;
}

// Main code
$length = 5;
$width = 10;

$area = calculateRectangleArea($length, $width);
displayResult($area);
