the main issue item_namex (x) could be 1, 2, 3, 4 ext

Answer 1

You are looking for variable variables in PHP:

$x = 7;
$var = 'item_name' . $x;
$$var = $_POST['item_name'. $x];  

and then you get $item_name7 with value you want. Also trailing concatenation of .'' in your right side of assignment is useless

Answer 2

foreach($_POST as $key=>$value){
    $$key=$value;
}

For every $key variable will be created and $value would be assigned to it
