How can proper variable scoping improve code readability and maintainability in PHP?

Proper variable scoping in PHP can improve code readability and maintainability by ensuring that variables are only accessible where they are needed. This helps prevent accidental variable overwriting or unintended side effects in the code. By following best practices for variable scoping, developers can make their code easier to understand and modify in the future. 

function calculateTotal($prices) {
    $total = 0; // Initialize the total variable within the function scope
    
    foreach ($prices as $price) {
        $total += $price;
    }
    
    return $total;
}
