Family Tree JSON Generator PHP

Question

我想实现JSON格式

    [{"name": "Niclas Superlongsurname",
  "class": "male node-item",
  "textClass": "emphasis",

  "marriages": [{

      "spouse": {
          "name": "Iliana",
          "class": "female"
      },
      "children": [{
          "name": "James",
          "class": "male",
          "marriages": [{
              "spouse": {
              "name": "Alexandra",
              "class": "female"
          },
      "children": [{
          "name": "Eric",
          "class": "male",
          "marriages": [{
            "spouse": {
              "name": "Eva",
              "class": "female"
            }
          }]
        }, {
          "name": "Jane",
          "class": "female"
        }, {
          "name": "Jasper",
          "class": "male"
        }, {
          "name": "Emma",
          "class": "female"
        }, {
          "name": "Julia",
          "class": "female"
        }, {
          "name": "Jessica",
          "class": "female"
        }]
      }]
    }]
  }]
},{
    "name": "Same level as Niclas",
    "class": "male",
}]

数据库表，我有类似的东西

id | name | userID | relatedID | parentID | level
1     Jon       1        0           3        6
2     Jan       1        1           0        6
3     Mum       1        0           0        5

UserID用于区分用户和其他家庭 RelatedID用于配偶目的 ParentID用于父母。

我试图以递归方式实现此目的但仅在第一级失败。有人可以在递归部分帮助我吗？

$currentLvl = $result[0]["level"];
        foreach($result as $id => $val)
        {

            // if(!in_array($val["relationshipID"], $doneArr))


            //parent
            if($val["parentID"] > 0)
            {
                $mainParentIndex = array_search($val["parentID"],  array_column($relationshipArray, 'id')); // $key = 2;
                $relationshipArray[$mainParentIndex]["marriages"][0]["children"][$childrenIndex]["name"] = $val["relationshipName"];
                $relationshipArray[$mainParentIndex]["marriages"][0]["children"][$childrenIndex]["class"] = strtolower($val["relationshipGender"]);     
                $relationshipArray[$mainParentIndex]["marriages"][0]["children"][$childrenIndex]["id"] = strtolower($val["relationshipID"]);        
                $childrenIndex++;


                //start


                //end

            }   
            else{
                // {
                if($val["relatedID"] == 0 && $val["parentID"] == 0)
                {
                    $relationshipArray[$ownSiblingsIndex]["name"] = $val["relationshipName"];
                    $relationshipArray[$ownSiblingsIndex]["class"] = strtolower($val["relationshipGender"]);    
                    $relationshipArray[$ownSiblingsIndex]["id"] = $val["relationshipID"];   
                    $doneArr[] = $val["relationshipID"];
                    $ownSiblingsIndex++;
                }


                //is a spouse
                if($val["relatedID"] > 0)
                { 
                    $mainSpouseIndex = array_search($val["relatedID"],  array_column($relationshipArray, 'id')); // $key = 2;
                    //echo $val["relationshipID"]."-".$val["relatedID"]."- ".$mainSpouseIndex."<br>";   
                    $relationshipArray[$mainSpouseIndex]["marriages"][0]["spouse"]["name"] = $val["relationshipName"];
                    $relationshipArray[$mainSpouseIndex]["marriages"][0]["spouse"]["class"] = strtolower($val["relationshipGender"]);
                    $relationshipArray[$mainSpouseIndex]["marriages"][0]["spouse"]["id"] = $val["relationshipID"];  
                    $doneArr[] = $val["relationshipID"];
                    $removeArr[] = $val["relationshipID"];
                }
            }
