将树结构转换为php数组

Question

我有树解决方案，但我想将其转换为数组......

 function generatePageTree($datas , $parent = 0)
$tree = '<ul>';
for($i=0, $ni=count($datas); $i < $ni; $i++){
    if($datas[$i]['parent_id'] == $parent){
        $tree .= '<li>';
        $tree .= $datas[$i]['ledger_account_name'];
        $tree .= $this->generatePageTree($datas, $datas[$i]['ledger_account_id']);
        $tree .= '</li>';
    }
}
    $tree .= '</ul>';
return $tree;
}

我希望这个树形结构以数组的形式..任何一个已经完成的请帮助.... 数组格式............

 array(
      id=>100, parentid=>0, name=>'a', children=>array(
        id=>101, parentid=>100, name=>'a', children=>array(
          id=>102, parentid=>101, name=>'a',
          id=>103, parentid=>101, name=>'a',
        )
      )
    )

function buildTree(array $elements, $parentId = 0) {
          $branch = array();

          foreach ($elements as $element) {

              if ($element['parent_id'] == $parentId) {
                  $children = $this->buildTree($elements, $element['ledger_account_id']);

                  if ($children) {

                      $element['children'] = $children;

                  }
                  $branch[$element['ledger_account_id']] = $element;
              }
          }

          return $branch;
      }
