How can debugging techniques be utilized to troubleshoot PHP scripts like the one discussed in the thread?

Issue: The PHP script is not displaying the expected output due to a syntax error or logical mistake. To troubleshoot this, we can use debugging techniques like printing variable values, using var_dump(), or step-through debugging with a tool like Xdebug. PHP Code Snippet: 

<?php

// Define variables
$num1 = 10;
$num2 = 5;

// Calculate the sum
$sum = $num1 + $num2;

// Output the result
echo "The sum of $num1 and $num2 is: $sum";

?>
