Array in a Loop Question

I have a form that gets repeated depending on number of members in a group(1 form surrounds all members). I separate the entries by assigning a count value to the names of the inputs (Ex. <input type=text name=address$count value=>). Does anyone know how I can pull the values back out of the $_POST[]? Example of ideal scenario that does not work: case "process1": for ($i=0;$i<$_POST[count];$i++) { $_POST[address$i] }
