after731 Says:

Jun 7, 2010 - Hmmm so when you use 'return' you need to add 'echo' to print the function?

Sep 23, 2010 - Basically, when you use the return function it returns whatever variable that follows the return statement. That is, when he echoed add(12, 343), the value that got put into the echo function is the value of $total which was $a + $b.He could have just as easily typed: $newVariable = add(12, 343); echo $newVariable;

Sep 24, 2010 - @admiral3131 echo prints something on the scree, return "brings" something from a function / variable

Dec 2, 2010 - if I really want to add those numbers can I just use the one on the past tutorials... the one with the basic math...

Diifusal Says:

Jan 2, 2011 - why do you use return? isn't it the same as using echo $total?

DR01D5 Says:

Jan 3, 2011 - It's not the same. You only use echo if you want it to appear on the website. For most of the functions you definitely don't want that. So you probably just want to continue working with the result "behind the scenes"

Jozekban Says:

Jan 4, 2011 - so what's the diffrence between echo $lol which &lol = &a +&b and return &lol which &lol = &a +&b

m0gria Says:

Jan 5, 2011 - no, it isnt! If you write echo $total, the text will be echoed. If you return $total, you can use the value of $total, outside of the function.
