父母和子女關係數組

我有一個由父母和子女組成的類別數組。有人可以幫助我使用parent_id和category_id與foreach循環在層次結構中排列數組。最頂層的Parent具有「零」的parent_id。請忽略除category_id和parent_id之外的其他字段。這是我的數組。父母和子女關係數組

你可以分享你預期的輸出？ –

如果您給我們您的預期結果，這將有所幫助 –

最外面的數組應該是parent_id「0」。裏面必須有基於parent_id的孩子。 parent_id只是其父項的category_if。 @SahilGulati –

考慮功能

function get_childs($arr, $parent_id = 0) { 
    $res = array(); 
    foreach ($arr as $row) { 
     if ($parent_id == $row['parent_id']) { 
       $childs = get_childs($arr, $row['category_id']); 
       $row['childs'] = $childs; 
       $res[] = $row; 
     } 
    } 
    return $res; 
}

然後用這個函數來得到家長和孩子的它

$res = get_childs($arr);
