Answer 1

can you change your code for this input:

Array
(
    [0] => Array
        (
            [text] => paris
            [nodes] => Array
                (
                    [jacque] => Array
                        (
                            [text] => jacque
                            [nodes] => Array
                                (
                                    [0] => 32.png
                                )
                        )

                    [anis] => Array
                        (
                            [text] => anis
                            [nodes] => Array
                                (
                                    [0] => 5384a97ee9d6b (2).pd
                                )
                        )
                )
        )

    [1] => Array
        (
            [text] => london
            [nodes] => Array
                (
                    [dodo] => Array
                        (
                            [text] => dodo
                            [nodes] => Array
                                (
                                    [0] => 148782.svg
                                    [1] => 333.png
                                )

                        )

                    [sd] => Array
                        (
                            [text] => sd
                            [nodes] => Array
                                (
                                    [0] => 1014-favicon.ico
                                )

                        )

                   )
        )
)

Answer 2

To change all of the child keys to numeric values, you can simply just use array_values()

Live Demo

for($i = 0; $i <= count($data) -1; $i++) { # This loops through each country
    $data[$i]['nodes'] = array_map(function($node) { # This preserves the parent text value
        return array_values($node); # [0] => Paris, [1] => array(...)
    }, $data[$i]['nodes']);
}

Output

[ ... => [ text => Paris, nodes => [ 0 => Paris, 1 => [ ... ] ] ... ] ... ]
