Now you can only return one value to the function right? Oh cool, the return command is pretty neat! Now you can only return one value to the function right?

Reason being you might want to use the function to do something else later on (i.e. string length) so in this case having it ECHO out as standard won't work.

At the end we just "return $total" at the end of the function. This can spare us define a new "$total" variable in each case. is not possible to define right $total in the function, and then in each “case” of switch, give the value of the choosen operationen.

Case is specifing the condition you are chosing. You can say case or switch statement, but you have to speific switch() { case "": } .
