Answer 1

If you know how many do you have:

for ($i=0; $i < $num_of_vars; $i++)
    echo $_POST['item_number'.$i]."
";

UPDATE: If not:

foreach($_POST as $k => $v) {
    $pos = strpos($k, "item_number");
    if($pos === 0)
        echo $v."
";
}

Gets all POST variables that are like "item_number"

UPD 2: Changed "==" to "===" because of piotrekkr's comment. Thanks
