Help with variables

[Anon]

Hi,

In my php script i'm trying to use a while statement to loop until a certain requirement is met, I also have variables which are named by questions.
eg. $Question_1 holds question 1
$Question_2 holds question 2 etc...

so in the while statement i need to use another variable to create the name of the variable which i'm trying to call. so i make something like

$Question = "$" . "Question_" . $Q_Num;
where $Q_Num is the number in the loop. this creates the variable name i need but now i need to know how i can call the variable name from $Question to be used as a variable rather than a string.

any help would be greatly appreciated. Thanks in advance to all who try.

Hi,
So if you want to access all these $question_# in a loop, have they been previously defined... or are they being defined in the loop...
Either way, would it not be much easier to use an array...
$question[1]="question 1" ;
$question[$Q_num] = "Question $Q_num";

It would be simple to increment or change your $Q_num every loop.

The array would still allow you to search for any requirements that end your loop...

Hope this helps,
Good luch
