A variable variable results in a second variable which is named for the *value of the first. So what I need is a sort of "inverse variable variable" to extract the *name of the first variable: $foo="bar" echo $foo //"bar" echo [something] //"foo" I ended up doing a clumsy workaround by altering $foo-- $foo="bar" $foo=array("foo"=>$foo) echo $foo[key($foo)]; //"bar" echo key($foo); //"foo" --but then I'm having to tell PHP the very info that I was hoping it'd dynamically tell me. Any other suggestions would be much appreciated! -- CC
