Refrence a variable?

[dkode]

I know this is a simple answer but my mind is blank..

I have multiple fields each with the name:
quantity_ID

where id is equal to a unique number

Now, once i submit the form how would i access these variables? Currently i have a foreach loop with all of the ID's. lets say i wanted to dump what quantity they submitted into a new variable, how would I do so? i know i've done this before but i just don't remember how now...

I think it was something like:
$[quantity_$id] or something like that?

to get all the POST vars into a function, do something like;

foreach($HTTP_POST_VARS as $key => $value)
submitValue($key, $value)

//where $key is the posted var name
//and $value is its content

but you were asking about variable variables.For those you would do somthing like this:

$variableName = "quantity_".$myNumber;
doSomethingWith($$variableName)

//notice the two dolar signs. This means the variable named the string in $variableName

you are close:

${"quantity_".$id}

should work.
