You can use the ECHO command we learned earlier to display more than one variable at a time.
Combining variables can be extremely useful. Take a look at this example...
<?php $phrase1 = "That's No Moon,"; $phrase2 = "It's a Space Station!"; echo "$phrase1 $phrase2"; ?>
This code example will show up in your web browser like this:
Neat, huh?
So, you can see where this might be useful, I hope?
You can also echo text and variables in the same statement by putting periods around the variable....like so...
<?php $items = 3; echo "You have purchased ".$items." items."; ?>
