How to make a certain array from the values ​​obtained via fgetcsv()?

Question

css

Hello everyone, there is a csv with the following data

How can I sort them into the following array:

$arr = [
    '0.1' => [            // значение с правой колонки
         'old' => 0.1, // значение с правой колонки
         'new' => ['0.1'] // значение с левой колонки
    ],
    ...,
   '01.11.1' => [
        'old' => '01.11.1',
        'new' => [
              '01.11.1',
              '01.11.11',
               ....
                '01.11.2',
           ]
]
          // и т.д.

I succeeded in displaying the data, it is not clear how, under the condition of repeating the old key, the new values ​​\u200b\u200bare entered into the previous array.

Answer 2

Move hands to the right place for such designers)
Either svg, or you need a solid color on the background.

Answer 3

the first block has :after the picture on the right, the second has :before the picture on the left, the third :after has the picture on the right.
Text centered, image positioned absolute. It seems nothing complicated. A picture is a line from one text to another.

Answer 4

It seems to me alone that this is a normal border?! 1 element - top, left and bottom are visible, middle - top, right, bottom, bottom - similar to the top. If you put down the elements well, it is generally imperceptible that this is a border.

Answer 5

Jeep)) In general, tear off the hands of the designer

Answer 6

$sorted = []; // Результирующий массив
        foreach ($lines as $line) { // $line[0] - old, $line[1] - new
            $sorted[$line[1]]['old'] = $line[1];
            $sorted[$line[1]]['new'][] = $line[0];
        }

If this is not it, then describe a specific set of input data (small) and what specific structure it should be converted to, we'll figure it out :)
