How can PHP developers ensure code readability and maintainability by following coding standards and consistent indentation?

To ensure code readability and maintainability in PHP, developers should follow coding standards such as PSR-1 and PSR-2. Consistent indentation helps make the code easier to read and understand, reducing the chances of errors and making it easier for other developers to collaborate on the project. 

<?php

// Example code snippet with consistent indentation
function calculateSum($a, $b)
{
    $sum = $a + $b;
    return $sum;
}

$result = calculateSum(5, 3);
echo "The sum is: " . $result;
