What are the best practices for maintaining code clarity and organization when using functions in PHP?

To maintain code clarity and organization when using functions in PHP, it is important to follow best practices such as using meaningful function names, keeping functions short and focused on a single task, organizing functions logically within the code, and documenting functions clearly with comments. 

// Example of well-organized and clear PHP code using functions

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

// Function to display a message with the calculated area
function displayAreaMessage($area) {
    echo "The area of the rectangle is: " . $area;
}

// Main code
$length = 5;
$width = 10;
$area = calculateRectangleArea($length, $width);
displayAreaMessage($area);
