How can syntax highlighting and other formatting techniques improve the readability and maintainability of PHP code, especially when shared in online forums for help and feedback?

Syntax highlighting and other formatting techniques can improve the readability and maintainability of PHP code by visually separating different elements such as keywords, variables, and strings. This can help developers quickly identify errors or understand the code structure. When sharing PHP code in online forums for help and feedback, using proper indentation, line breaks, and comments can make it easier for others to provide accurate assistance.

<?php

// Example PHP code snippet with proper syntax highlighting and formatting

function calculateSum($num1, $num2) {
    $sum = $num1 + $num2;
    return $sum;
}

$result = calculateSum(10, 20);
echo "The sum is: " . $result;

?>
