What are the benefits of using proper formatting and structure in PHP code for readability and maintenance?

Proper formatting and structure in PHP code improve readability and maintenance by making the code easier to understand and navigate for developers. It also helps in identifying and fixing errors quickly, as well as promoting consistency in coding practices.

<?php

// Badly formatted code
$variable='Hello';
if($variable=='Hello'){echo 'World';}

// Properly formatted code
$variable = 'Hello';
if ($variable == 'Hello') {
    echo 'World';
}

?>
