What are the potential pitfalls of not properly formatting PHP code, and how can this impact the functionality of the code?

Improperly formatting PHP code can lead to syntax errors, making the code difficult to read and maintain. This can result in unexpected behavior or even cause the code to break. By following proper formatting conventions, such as indenting code blocks and using consistent spacing, you can improve the readability and maintainability of your PHP code. 

// Properly formatted PHP code snippet
<?php

function addNumbers($num1, $num2) {
    return $num1 + $num2;
}

$result = addNumbers(5, 10);
echo $result;

?>
