Let me start by saying there is nothing wrong with the above and it's
doing exactly what the OP needed. However, when I use variable
variables, I prefer to use the following notation:
${$foo}
It makes the coder's intention clear and makes it so that it can't be
mistaken for a possible typo when someone comes in after the fact to
maintain the code.
And When I use this and when i use that. Oh i like this ^_^
Btw. my working buddys said on first view your example looked more wrong.
Try it and see. ;)
And on top of that, i wont let anyone code in my PHP docs who doesn't know
what $$var is or does!!
Agreed. But there have been a few times when I accidently added in an
extra $ to the variable and, consequently, didn't get the results I
expected.
thnx,
Chris
