How can I create an associative array using for each?

I am selecting checkboxes and want to save in an associative array with current page number $_GET['page_no'] as it's index, but only 1 value goes in, why no other?

$pageno = $_GET['page_no']; //Say page no is 1
$_SESSION['selected_vals'] = array();
foreach($_POST['record_num'] as $throw_rec_nums) {
    $_SESSION['selected_vals'][$pageno] = $throw_rec_nums;
}

What I expect

$_SESSOION['selected_val'] (
   [1] => 24
   [1] => 46
   [1] => 56
)

But I only get 24 even if 3 checkboxes are selected

Note: $_GET['page_no'] is returned as array

You cannot use an array as array index. You will have to iterate over $pageno too, for example with next():

$array[current($pageno)] = ...;
next($pageno);

Note that this will only work if you make sure rt that $pageno actually IS an array and contains enough elements.

Only 1 value goes in because your are replacing $_SESSION['selected_vals'][$pageno] value on each loop of foreach.

try create a counter to index it

it is a option

$_SESSION['selected_vals'] = array();
$_SESSION['selected_vals'][$pageno] = array();
foreach($_POST['record_num'] as $throw_rec_nums) {
    $_SESSION['selected_vals'][$pageno][] = $throw_rec_nums;
}

$pageno is not incrementing. In order for more than one value to be added to the array, it needs to be incremented while in the loop.

A solution would be something like:

$_SESSION['selected_vals'][$pageno][] = $throw_rec_nums;

That way all record numbers would be saved to the array at the page number specified.
