How can code readability and maintainability be improved in PHP scripts, especially when working with image comparison algorithms?

When working with image comparison algorithms in PHP scripts, code readability and maintainability can be improved by breaking down the algorithm into smaller, modular functions with descriptive names. This helps in understanding the logic of the algorithm and makes it easier to maintain and debug in the future. 

// Example of breaking down image comparison algorithm into smaller functions

// Function to load image from file
function loadImage($filePath) {
    // Code to load image from file
}

// Function to convert image to grayscale
function convertToGrayscale($image) {
    // Code to convert image to grayscale
}

// Function to calculate image similarity
function calculateSimilarity($image1, $image2) {
    // Code to calculate image similarity
}

// Main script
$image1 = loadImage("image1.jpg");
$image2 = loadImage("image2.jpg");

$grayImage1 = convertToGrayscale($image1);
$grayImage2 = convertToGrayscale($image2);

$similarity = calculateSimilarity($grayImage1, $grayImage2);

echo "Image similarity: " . $similarity;
