Re: [PHP-DB] Variables in a loop From: Jason G. (blair <email protected>)

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];
