What are best practices for structuring PHP code to improve readability and prevent syntax errors like missing semicolons or brackets?

To improve readability and prevent syntax errors in PHP code, it is essential to follow best practices such as consistent indentation, proper naming conventions, and clear commenting. Additionally, using an IDE with syntax highlighting and error checking can help identify missing semicolons or brackets before running the code.

<?php

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

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

?>
