How can PHP developers improve the readability and maintainability of their code?

PHP developers can improve the readability and maintainability of their code by following coding standards, using meaningful variable names, breaking down complex code into smaller functions, and adding comments to explain the logic behind the code. 

// Example of improving readability and maintainability of PHP code

// Using meaningful variable names
$firstName = 'John';
$lastName = 'Doe';

// Breaking down complex code into smaller functions
function calculateTotal($price, $quantity) {
    return $price * $quantity;
}

$total = calculateTotal(10, 5);

// Adding comments to explain the logic behind the code
// This function calculates the total price based on the price and quantity
