What are the best practices for formatting PHP code to ensure readability and maintainability, especially when posting on forums with character limits?

When posting PHP code on forums with character limits, it's important to format the code properly for readability and maintainability. One way to do this is by using indentation to clearly show the structure of the code. Additionally, using proper spacing around operators and keywords can make the code easier to read. Finally, consider breaking long lines of code into multiple lines to fit within the character limit without sacrificing readability. 

<?php

// Example PHP code snippet with proper formatting
function calculateSum($num1, $num2) {
    $sum = $num1 + $num2;
    return $sum;
}

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

?>
