Return in function

[Foser]

function Adding($number) {
$number = $number+5;
return $number;
}
<br>
$number = 5;
$newnumber = Adding($number);
<br>
echo "$newnumber"; 

 

I was reading this tutorial but I never understood why and what return does. and why place the variable statement after this?

return

 

You can use variables after that.

Quick Example

 

<?php
echo "Hello ";
echo MakeBold("World");

function MakeBold($foo)
{
$foo = "<b>".$foo."</b>";
return $foo;
}
?>

 

So when MakeBold is called the variable "World" is sent to the function..

the function does it stuff (add < b> to the starr and < /b> to the end) then returns the value back to where it was called from.

 

make sense ?
