PHP noob's got trouble getting data from forms

I'm teaching myself PHP & MYSQL so beware of my high noob level at this, but I ran into this problem :
This code is in a form and in a cell of a table:

Code:

 for ( $i=8; $i<$numfields; $i++ ) 


       {


        $input = "inp_$i";


        <input type=text name=$input size=2 value=0>                


       }

- I deleted some non-interesting stuff - ok so now this loop creates :
inp_8, inp_9 ............... inp_17 or so.

when I submit the code, this information is available :
inp_8 and $inp_8 ( the value of inp_8 )
this is true, I tested it.

But now I want to make this :

Code:

 for ( $i=8; $i<$numfields; $i++ ) 


       {


                echo $(inp_$n);              


       }

but I cannot get that to work ! I've been trying all morning with the variable-variables were :
$input = inp_$i;
$$input = $($input);

but that's pretty much the same problem.

Any clues ?

Oops, found it out myself :

this is the solution :

Code:

$input = "inp_$i";


echo "$ {$input}";

Yep! I would remove the space though

Code:

echo "${$input}";
