How can PHP developers ensure that their code is easily understandable and maintainable by others?

To ensure that PHP code is easily understandable and maintainable by others, developers can follow best practices such as using meaningful variable names, writing clear comments, breaking down complex tasks into smaller functions, and adhering to coding standards like PSR-12. 

// Example of well-commented and organized PHP code
function calculateTotal($price, $quantity) {
    // Calculate the total cost
    $total = $price * $quantity;
    
    // Apply a discount if the quantity is greater than 10
    if ($quantity > 10) {
        $total *= 0.9; // 10% discount
    }
    
    return $total;
}
