In what ways can inconsistent formatting and lack of separation of processing logic and output affect the maintainability of PHP code?

Inconsistent formatting and lack of separation of processing logic and output can make PHP code difficult to read and maintain. To improve maintainability, it's important to follow a consistent coding style, separate processing logic from output generation, and use proper indentation and comments for clarity. 

<?php

// Processing logic
$data = fetchDataFromDatabase();

// Output generation
foreach ($data as $item) {
    echo "<div>";
    echo "<h2>{$item['title']}</h2>";
    echo "<p>{$item['description']}</p>";
    echo "</div>";
}

?>
