Add array to array without key IDs? - PHP

Question

I have a big array which looks like this:

array(2) {
  ["Final Fantasy VII"]=>
  array(5) {
    ["rows"]=>
    array(2) {
      [0]=>
      array(6) {
        ["price"]=>
        string(5) "11.69"
        ["price_old"]=>
        string(4) "4.66"
        ["currency"]=>
        string(4) "euro"
        ["portal"]=>
        string(0) ""
        ["link"]=>
        string(77) "https://de.gamesplanet.com/game/final-fantasy-vii-download--1001-1?ref=gmkeys"
        ["shop"]=>
        string(4) "9507"
      }
      [1]=>
      array(6) {
        ["price"]=>
        string(5) "14.99"
        ["price_old"]=>
        ...
      }
    }
  }

 ["Battlefield 1"]=>
  array(3) {
    ["rows"]=>
    array(2) {
      [0]=>
      array(6) {
        ["price"]=>
        ...
      }
      [1]=>
      array(6) {
        ["price"]=>
        ...
      }
    }
  }
}

And I want to get only certain parts of this array where the name is matching my searched title. So, I use this code for that:

function createACFRepeater($title){
    $repeater = array();

    if(searchForGameXML($title)){

        $count = count($GLOBALS["productsXML"][$title]['rows']);

        for($i = 0; $i < $count; $i++){
            array_push($repeater, $GLOBALS["productsXML"][$title]['rows'][$i]);
        }

        return $repeater;
    }else{
        return $repeater;
    }
}

My problem now is that the the $repeater array looks like this:

array(2) {
  [0]=>
  array(6) {
    ["price"]=>
    string(5) "19.98"
    ["price_old"]=>
    ...
  }
  [1]=>
  array(6) {
    ["price"]=>
    string(4) "7.99"
    ["price_old"]=>
    ...
  }
}

There is a numeric key which is pointing to the array [0] => .... But what I want is simply an array in a array without any associative relations...

How can I create an array which looks like this:?

array(2) {
      array(6) {
        ["price"]=>
        string(5) "19.98"
        ["price_old"]=>
        ...
      }
      array(6) {
        ["price"]=>
        string(4) "7.99"
        ["price_old"]=>
        ...
      }
    }

Greetings and Thank You!

According to the array definition it is impossible. Any array item must have key and value, documentation for array starts from:

An array in PHP is actually an ordered map. A map is a type that associates values to keys

I need this array for a plugin. Watch here: advancedcustomfields.com/resources/update_field. And there, the array looks like this:

$value = array( 	array( "sub_field_1" => "Foo1", "sub_field_2" => "Bar1", "acf_fc_layout" => "layout_1_name" ), 	array( "sub_field_x" => "Foo2", "sub_field_y" => "Bar2", "acf_fc_layout" => "layout_2_name" ) );

But maybe you have an answer to this one also? support.advancedcustomfields.com/forums/topic/…

right! but if you write $value[0] you receive ` array( "sub_field_1" => "Foo", "sub_field_2" => "Bar" )`. If you omit indexes they are auto-incremented. It does not mean that array does not have indexes at all

okay, thank you! - I got confused by the documentation of the ACF plugin

I changed it. It was easier for me to read beacuse of the examples... Do you have a idea to the ACF support link?

@lubart your link isn't working properly, you added http:// at the end of the link :)

You will always have numeric keys. As @lubart already said: it's impossible to have an array without keys. Btw., all of the the follwing arrays are completely equal:

$array1 = array([0] => array([0] => 'hi', [1] => array([0] => '23.5')));

$array2 = array(array('hi', array('23.5')));

$array3 = [['hi', ['23.5']]];

$array4 = [ [0] => [ [0] => 'hi', [1] => [ [0] => '23.5' ] ] ];
