Variablename into string

Hi! :-)

I want to put a variablename into a string and don't know how?

e.g.: $var=123; // some variable
... // magic statement (what to put here?)
$varname == "var"; //this should be the result

Uhm... why would you need this?
How can you ever define a var and then forget what the name of that var was?

here is a posting in another forum that deals with it (however it's a php v3 forum):

The best suggestion I can think of would be something like:

while(list($k,$v)=each($GLOBALS)) {
    if($k[0]=="a") echo "$k: $v<br>\n";
}

This prints out all the variables in the PHP symbol table whose names
start with "a".

I am quite interested why you would want to do this as well.

Thanks a lot for your help, matto! Have a nice weekend! :-)
