I believe what Jochem is trying to tell you is that when you assign the string variable, the variable names are expanded to their values, so the names are no longer available.
exactly - nicely put Jim.
Consider this: $partname='widget'; $amount=100; $string="This $partname costs $amount dollars"; /* $string now equals "This widget costs 100 dollars", so when you pass it to your function, it has no way to know for sure what the variables were, or that there even were ANY variables involved in the generation of the string. The variable NAMES are not passed because PHP expands them to their values and sets $string accordingly. */ $string='This $partname costs $amount dollars'; $string now equals "This $partname costs $amount dollars". In this case, I used single quotes. The values are not expanded and the variable NAMES are passed. The VALUE of the variables are not. So you could then have a function look for any word that starts with a $ and return an array of names.
hopefully thats clear to the OP now - and he can [re]state his goal in order that we might point him into a more fruitful direction!
That all being said, what in the world are you trying to do with this? I bet you $1.78 (the change in my desk drawer) there is a much better way to solve whatever problem it is than the way you are trying here.
yeah 'Superman' explain what it is you want to do AND why - then maybe we can give you some help - what you are currently asking is impossible (well actually Jay Blanchard hinted at a way to do it but I firmly believe that its conceptually over your head atm and very probably not a good solution to what you want to acheive - which is not to say that Jays hint was crap or wrong; more like the problem you posed originally is moot.)
JM Because it ruins the flow of the conversation.
evil genius ;-)
