define array variable inside array

Question

How to define variable inside array without key? This doesnt working and I dont know how...

$array = array("list" => array());

$list = $array["list"][] = array("sub_list" = array());
$list["sub_list"][] = "text1";
$list["sub_list"][] = "text2";
$list["sub_list"][] = "text2";

$list2 = $array["list"][] = array("sub_list" = array());
$list2["sub_list"][] = "text1";
$list2["sub_list"][] = "text2";
$list2["sub_list"][] = "text3";

Needed result:

$array = array(
   "list" => array(
      array(
        "sub_list" = array("text1", "text2", "text3")
      ),
      array(
        "sub_list" = array("text1", "text2", "text3")
      )
    )
);

It's not used in loop or for/foreach!

Is there any reason why you don't want to declare the array using the second method? — Nigel Ren

@Dharman my mistake, ofc with => but same problem - sub_list are always empty arrays — alexso

Your question isn't clear. Can you rephrase the problem, please? — waterloomatt

$array = [
    'list' => []
];

$list = [];
$list[] = 'text1';
$list[] = 'text2';
$list[] = 'text3';
$array['list'][]['sub_list'] = $list;

$array['list'][]['sub_list'] = $list;

$list = [];
$list[] = 'text4';
$list[] = 'text5';
$list[] = 'text6';
$array['list'][]['sub_list'] = $list;

And you will have :

$array = array(
   "list" => array(
      array(
        "sub_list" => array("text1", "text2", "text3")
      ),
      array(
        "sub_list" => array("text1", "text2", "text3")
      ),
      array(
        "sub_list" => array("text4", "text5", "text6")
      )
    )
);

code working as I wrote, but impossible add something to exists array with $array['list'][]["SOMETHING_NEXT"] is created new array, show my request below... thanks

I don't know how your script work or need to work only with your question. So you need to store the index when you create a new list array. Then you can use the index to add something like $array['list'][0]['SOMETHING_NEXT'] as same deep as sub_list

I think something like $var = $array['list'][] but its maybe impossible, okay... index $i++; and $array['list'][ $i ]['SOMETHING_NEXT'] how to identify key

$array["list"][] = array("sub_list" => array());
$list= [];
$list[] = array("text1", "text2", "text3");
$list[] = array("text1", "text2", "text3");
$array["list"][]["sub_list"] = $list;

althought it's array inside array and this array is also in array

i need $array["list"][] as variable, when is called $array["list"][]["sub_list"] = $list; is created new one array, i need add "sub_list" to first array
