How to refer to the parent in JSON?

Question

PHP

// читаем файл с закладками в формате JSON
$str = file_get_contents('Bookmarks');
$ar = json_decode($str);
$b_bar = $ar->roots->bookmark_bar->children;
$other = $ar->roots->other->children;
$synced = $ar->roots->synced->children;
$marks = array();

function recursiveJSON2ARRAY($obj){
  global $marks;
  foreach($obj as $v){
    if(isset($v->children) && is_array($v->children) && count($v->children) > 0){
      $parentname = $v->name;
      foreach($v->children as $child){
        if(isset($child->url)){
          $marks[$child->date_added] = array('parentname'=>$parentname, 'name'=>$child->name, 'url'=>$child->url);
        }
        else{
          recursiveJSON2ARRAY($v->children);
        }
      }
    }
    else{
      if(isset($v->url)){
        // здесь надо получить доступ к родителю $v (КАК???)
        //$parentname = $obj->name;
        $marks[$v->date_added] = array('parentname'=>$parentname, 'name'=>$v->name, 'url'=>$v->url);
      }
    }
  }
}

if($b_bar){
  recursiveJSON2ARRAY($b_bar);
}
if($other){
  recursiveJSON2ARRAY($other);
}
if($synced){
  recursiveJSON2ARRAY($synced);
}

//krsort($marks); // Reverse sort the bookmarks by date added
 
$table = '<table cellspacing="2" cellpadding="2" border="1" width="600"><tr><td><b>Date</b></td><td><b>Name</b></td><td><b>URL</b></td></tr>';
foreach($marks as $date=>$mark)
{
  $table .= '<tr><td>'.date('d-m-Y', $date).'</td><td>'.$mark['parentname'].'</td><td>'.$mark['name'].'</td><td><a href="'.$mark['url'].'" target="_blank">'.$mark['url'].'</a></td></tr>';
}
$table .= '</table>';
 
//echo $table;
echo '<pre>';
print_r($marks);
echo '</pre>';

Answer 1

Here is a working example of what was needed))) Finally, I finished it.

// читаем файл с закладками в формате JSON
$str = file_get_contents('Bookmarks');
$ar = json_decode($str);
$root = $ar->roots;
$marks = array();

function normalizeChromiumTime($time) {
    return date("H:i:s d-m-Y", ($time - 11644473600000000) / 1000000);
}

function recursiveJSON2ARRAY($obj, $parent = null){
  global $marks;
  foreach($obj as $v){
    if(isset($v->children) && is_array($v->children) && count($v->children) > 0){
      $parentname = $v->name;
      foreach($v->children as $child){
        if(isset($child->url)){
          $date_added = normalizeChromiumTime($child->date_added);
          $marks[$child->date_added] = array('parentname'=>$parent." -> ".$parentname, 'date'=>$date_added, 'name'=>$child->name, 'url'=>$child->url);
        }
        else{
          recursiveJSON2ARRAY($v->children, $parent." -> ".$parentname);
        }
      }
    }
    else{
      if(isset($v->url)){
        $date_added = normalizeChromiumTime($v->date_added);
        $marks[$v->date_added] = array('parentname'=>$parent, 'date'=>$date_added,  'name'=>$v->name, 'url'=>$v->url);
      }
    }
  }
}

foreach($root as $childrenElement){
  if(isset($childrenElement->children) && is_array($childrenElement->children)){
    recursiveJSON2ARRAY($childrenElement->children, $childrenElement->name);
  }
}

//krsort($marks); // Reverse sort the bookmarks by date added
 
$table = '<table cellspacing="2" cellpadding="2" border="1" width="600"><tr><td><b>Дата создания</b></td><td><b>Категория</b></td><td><b>Имя</b></td><td><b>URL</b></td></tr>';
foreach($marks as $date=>$mark){
  $table .= '<tr><td>'.$mark['date'].'</td><td>'.$mark['parentname'].'</td><td>'.$mark['name'].'</td><td><a href="'.$mark['url'].'" target="_blank">'.$mark['url'].'</a></td></tr>';
}
$table .= '</table>';

echo $table;

Just pass the name of the parent to the function with a default parameter, whatever. And give up globals, this is harmful, nightmares begin to dream at night, early graying.

function recursiveJSON2ARRAY($obj, $parentname = null)
{
  global $marks;
  foreach ($obj as $v) {
    if (isset($v->children) && is_array($v->children) && count($v->children) > 0) {
      $parentname = $v->name;
      foreach($v->children as $child) {
        if(isset($child->url)){
          $marks[$child->date_added] = array('parentname'=>$parentname, 'name'=>$child->name, 'url'=>$child->url);
        } else {
          recursiveJSON2ARRAY($v->children, $parentname);
        }
      }
    } else {
      if (isset($v->url)) {
        // если $parentname не передали, то он null
        $marks[$v->date_added] = array('parentname'=>$parentname, 'name'=>$v->name, 'url'=>$v->url);
      }
    }
  }
}

if ($b_bar) {
  recursiveJSON2ARRAY($b_bar);
}
