why must the name be dynamic?

i suppose you could use a hidden form field with a known name, and set the value to the dynamic name of the select menu. then use the known name to find the dynamic name when receiving the form.

if you could provide more info, there may be a much easier solution.

yes, that will work just fine but it will group them all together into 1 array. if you want the selections from each menu to be seperated from other menus, use a multidimensional array.

<select name="number[0][]" ...

<select name="number[1][]" ...
or
<select name="number[foo][]" ...

<select name="number[bar][]" ...

print_r($_POST['number']);

$select_menus = $_POST['number'];
foreach ($select_menus as $menu_name => $selections) {
    echo "$menu_name\n";
    foreach ($selections as $s) {
        echo "  $s\n";
    }
