Gary,
To add to the conversation ...
You created a function to pass something through it, to process something and
now you want to get something back, right? That's what return does. It gets
something back for your effort.
You could simply:
echo addslashes($var);
But let's say you do it a hundred times in the course of a script. You don't
want to take up a hundred lines of code doing:
echo addslashes($var);
... so you create a function like Eric has below, which takes up 3 or 4 lines of
code, but has the capacity to repeat the same line of code 100 times.
