What are the potential pitfalls of not properly formatting code in PHP forums and how can users improve their formatting skills?

Improperly formatted code in PHP forums can make it difficult for other users to read and understand the code, leading to confusion and potential errors. Users can improve their formatting skills by using proper indentation, commenting their code, and following common coding standards.

<?php

// Example of properly formatted PHP code
function calculateSum($num1, $num2) {
    $sum = $num1 + $num2;
    return $sum;
}

// Call the function
$result = calculateSum(5, 10);
echo "The sum is: " . $result;

?>
