PHP: get array of array from an inner foreach

Question

I'm trying to get an array of the arrays in an inner foreach loop.

My code looks something like this:

foreach ( $parent_terms as $parent_term ) {
    $outer_array = array();

        foreach ( $child_terms as $child_term ) {
            $inner_array = array();
            $inner = 'something';
            $inner_array[] = $inner;
            $outer_array[] = $inner_array;

            print_r($inner_array);
        }

      print_r($outer_array);
}

when I print outer array it starts again for each inner array.

what it suppose to be $child_terms? how does $parent_terms contains? — Chemaclass

Because you reinitialize it all the time $outer_array = array();. Can you share a demo of your issue and your expected output? — mighty_dev

Update code:

foreach($parent_terms as $parent_term ) {
        $outer_array = array();
        foreach ( $child_terms as $child_term ) {
            $inner_array = ['something'];
            array_push($outer_array,$inner_array);
        }

      print_r($outer_array);
}

What is the difference between OP's code and your code? Maybe I have overlooked something.
