What is the best way to calculate and display the difference between two values in PHP?

To calculate and display the difference between two values in PHP, you can subtract the second value from the first value to get the difference. You can then format and display the result using echo or print statements. Additionally, you may want to consider using number_format() function to format the result with a specific number of decimal places.

$value1 = 10;
$value2 = 5;

$difference = $value1 - $value2;

echo "The difference between $value1 and $value2 is: " . number_format($difference, 2);
