What is the difference between using commas and not using commas in PHP echo statements?

Using commas in PHP echo statements allows you to separate multiple values or variables to be echoed out without concatenating them. This can make the code more readable and easier to manage. On the other hand, not using commas requires concatenating the values or variables using the dot (.) operator, which can be more cumbersome. 

// Using commas in echo statement
echo "Hello", " ", "World!";

// Not using commas in echo statement
echo "Hello" . " " . "World!";
