How can PHP functions be modularized and organized to improve readability and maintainability?

To improve readability and maintainability of PHP functions, they can be modularized by breaking them down into smaller, more focused functions that perform specific tasks. This helps in organizing the code logically and makes it easier to understand and maintain. Additionally, grouping related functions together in separate files or classes can further enhance the organization of the code. 

// Example of modularizing PHP functions by breaking them down into smaller, more focused functions

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

// Function to calculate the perimeter of a rectangle
function calculateRectanglePerimeter($length, $width) {
    return 2 * ($length + $width);
}

// Usage of the functions
$length = 5;
$width = 3;

$area = calculateRectangleArea($length, $width);
$perimeter = calculateRectanglePerimeter($length, $width);

echo "Area: $area, Perimeter: $perimeter";
