Sorting Dotted Numbers in JSON & PHP

In my project with PHP Inside the JSON is the data I keep. And each of these data has sequence numbers 1.1, 1.1.1, 1.1.2, 1.1.3, …, 1.1.10.

When I sorted, I noticed that 1.1.10 came after 1.1.1, whereas 1.1.9 wasn’t there yet.

Because it sorts alphabetically. And I don’t know how to deal with it!

Edit: Added sample JSON data.

{
  "2": {
    "sirano": "1",
    "personal": "4",
    "tarihler": {
      "baslangic": "2022-11-10",

$data = json_decode($proje->JSONData, true); 
function order($a, $b) 
{
    return $a['sirano'] - $b['sirano'];
}
uasort($data, 'order');

I tried like this, but the result is clear! Please help me, I’m going crazy!

Answer

You need to use version_compare function inside of sort function:

<?php

$json = json_decode('{
  "2": {
    "sirano": "1",
    "personal": "4",
    "tarihler": {
      "baslangic": "2022-11-10",
      "bitis": "2022-11-17"
    },
    "ilerleme": "0"
  },
  "124": {
    "sirano": "1.1.1",
    "personal": "4",
    "tarihler": {
      "baslangic": "2022-11-10",
      "bitis": "2022-11-17"
    },
    "ilerleme": "0"
  },
  "125": {
    "sirano": "1.1.2",
    "personal": "4",
    "tarihler": {

    "ilerleme": "0"
  },
  "130": {
    "sirano": "1.1.7",
    "personal": "4",
    "tarihler": {

  "133": {
    "sirano": "1.1.10",
    "personal": "4",
    "tarihler": {
      "baslangic": "2022-11-10",
      "bitis": "2022-11-17"
    },
    "ilerleme": "0"
  },
  "134": {
    "sirano": "1.2",
    "personal": "4",
    "tarihler": {
      "baslangic": "2022-11-10",
      "bitis": "2022-11-17"

    "ilerleme": "0"

  "135": {

      "bitis": "2022-11-17"
    },
    "ilerleme": "0"
  }
}',true);

function order($a, $b) 
{
    return version_compare($a['sirano'], $b['sirano']);
}
usort($json, 'order');

echo'<pre>';
print_r($json);

For descending change places $b abd $a variables:

return version_compare( $b['sirano'],$a['sirano']);
