The solution using array_keys, array_map and array_combine functions:

// $arr is your initial array
$result = [];
foreach($arr as $v){
    $keys = array_keys($v);
    $data = call_user_func_array('array_map', [null] + $v);
    $result[] = array_map(function($item) use($keys){ 
        return array_combine($keys, $item); 
    }, $data);
}

print_r($result);

The output:

Array
(
    [0] => Array
        (
            [0] => Array
                (
                    [caption1] => gfdhgfjhg
                    [caption2] => shgjgh
                    [banner_image] => assets/images/page_content/img_namT7.jpg
                )

            [1] => Array
                (
                    [caption1] => dfhfgjghk
                    [caption2] => dhfgkgjl
                    [banner_image] => assets/images/page_content/img_R8mzP.jpg
                )

        )

    [1] => Array
        (
            [0] => Array
                (
                    [heading] => 
                    [pragraph] => 
                )
        )
)
