php - Creating an array without keys in a loop

Question

This might be a brain fart, since it's a late day, but I'm stuck here.

I need to take a $_POST value from a select box. (It's an array), and convert it to a simple array that doesn't have any keys.

Here's the print_r from the item:

Array ( [0] => 19 [1] => 18 [2] => 21 )

Problem is, I need an array that looks like this:

Array(19,18,21)

Whenever I try to foreach() through the form field, I have to do something like this:

$row[] = $val;

But that leaves me with a numerical index.

What am I missing?

Thanks.

Answer 1

you can't have an array without keys.

Array(19,18,21)

this array has keys 0,1 and 2.
