What are some best practices for organizing and structuring PHP code to prevent syntax errors?

To prevent syntax errors in PHP code, it is essential to follow best practices for organizing and structuring the code. This includes using proper indentation, consistent naming conventions, and commenting code effectively. Additionally, breaking down complex code into smaller, manageable functions can help identify and resolve syntax errors more efficiently.

<?php

// Example of well-organized PHP code to prevent syntax errors
function calculateSum($num1, $num2) {
    $sum = $num1 + $num2;
    return $sum;
}

$num1 = 10;
$num2 = 20;

$result = calculateSum($num1, $num2);
echo "The sum is: " . $result;

?>
