Re: Variables in a loop

If you have a string that is the name of an input field, you can do one of 3 things: Ex: $sName = "input".$i; //result = "input1" $sName = "input".$i; //result = "input2" etc... 1: Variable Variables $value = $$sName; 2: If you posted the form $value = $HTTP_POST_VARS[$sName]; 3: If you used GET with the form $value = $HTTP_GET_VARS[$sName]; Regards, -Jason Garber IonZoft.com At 09:10 AM 10/30/2001 +0100, * R&zE: wrote:

Any idea how to "read" the value of that string? Thanks for your help.
