Iterating varibales

I have a site which uses two pages. The first page generates an HTML form with multiple rows which is then POSTed to the second page. Sometimes on the first page I have to create multiple rows of INPUT fields. To allow a dynamic number of INPUT fields (say someone wants to add seven new numbers to there online address book), set up a while look and echo "<INPUT TYPE=text NAME=input_field".$inc.">"; where $inc is the incremented variable in a loop. The result is something like this: <INPUT TYPE=text NAME=input_field0> <INPUT TYPE=text NAME=input_field1> <INPUT TYPE=text NAME=input_field2> The difficulty comes when I try to access these variables on the second page. Currently I am using a script like this: $String = 'input_field'.$inc; echo($$String); Sometimes my code requires multiple variables and conditions. When this happens, using the above code is confusing a lengthy. Is there a way to simplify this code at all? _________________________________________________________ Do You Yahoo!?
