For this PHP exercise, write a script using the following variable:
Single quotes and double quotes don't work the same way in PHP. Using single quotes (' ') and the concatenation operator, echo the following to the browser, using the variable you created: What goes around comes around.
Here's the script:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
The point of this exercise is to use the period (".") concatenation operator. Using double quotes (" "), you could have included the variables in you string, and PHP would print them as intended. If your output doesn't look right, be sure you have included the appropriate spaces inside the quotes.
See the output of the script in a separate window here. You can also view the output's HTML source from the new window, if you need to check that.
