PHP-如何将数组中的数据显示到树或表中

目前，我已经从SELECT中检索到数据，并将其转换为PHP assoc数组。于是，我得到了这个数组。

[0] => array
(
    [Gattung] => 'Gattung_A'
    [Untergattung] => null
    [Sektion] => null
    [Untersektion] => null
    [Serie] => null
    [Unterserie] => null
    [Art] => 'Art_A'
    [Unterart] => null
    [Varietaet] => null
    [SubVarietaet] => null
    [Form] => 'Form_A'
    [Unterform] => null
    [SpezialForm] => null
    [Hybride] => null
    [Blendling] => null
    [Sorte] => null
)
[1] => array
(
    [Gattung] => 'Gattung_A'
    [Untergattung] => null
    [Sektion] => null
    [Untersektion] => null
    [Serie] => null
    [Unterserie] => null
    [Art] => 'Art_B'
    [Unterart] => null
    [Varietaet] => 'Variant_G'
    [SubVarietaet] => null
    [Form] => 'Form_B'
    [Unterform] => null
    [SpezialForm] => null
    [Hybride] => null
    [Blendling] => null
    [Sorte] => null
)
[2] => array
(
    [Gattung] => 'Gattung_B'
    [Untergattung] => null
    [Sektion] => null
    [Untersektion] => null
    [Serie] => null
    [Unterserie] => null
    [Art] => 'Art_C'
    [Unterart] => null
    [Varietaet] => 'Variant_A'
    [SubVarietaet] => null
    [Form] => null
    [Unterform] => null
    [SpezialForm] => null
    [Hybride] => null
    [Blendling] => null
    [Sorte] => null
)
......... 
Nearly ~300k records

到目前为止，我已经使用array_unique将我的数组固定为基于唯一值的一维数组。这是我的结果：

(
  [0] => 'Gattung|Gattung_A'
  [1] => 'Art|Art_A'
  [3] => 'Form|Form_A'
  [5] => 'Art|ArtB'
  [7] => 'Varietaet|Variant_G'
  [9] => 'Form|Form_G'
  [11] => 'Gattung|Gattung_B'
  [13] => 'Art|Art_C'
  [15] => 'Varietaet|Variant_A'
}

然而，我的结果并没有很好地分组。我需要在页面上显示它，所以类似于构建一个层次系统。

问题：@梅尔西：我希望我的第二次编辑能净化我的提问。

如何将数据显示到树中表格（请参见编辑2）或表格（请参阅编辑1）？

谢谢。

编辑1:

我正在做的是在几个表中创建类似FULLTEXT搜索的东西。这是连接所有表的查询：（所有FK都有每个表id的索引）

    tH.Hybride LIKE #14_Word# oR
    tBL.Blendling LIKE #15_Word# OR
    tSo.Sorte LIKE #16_Word#

我知道使用LIKE %xxx% OR是一个繁重的过程。如果你想给我另一种建议，那没关系。

我的预期结果是：

第2版：简明问题

或者以树形，

                   ----- Art A ------ Form A
                   |               |
                   |               -- Form B
1.   Gattung A ----|---- Art B ------ Form B ---- Variant G
2.   Gattung B --------- Art C ------ Variant A 
 ... And so on.

谢谢你的评论。

这是我对你问题的新答案，它避免了空行，如果你需要避免空行或需要其他东西，请告诉我。

我已经修复了第147行和第161行（对于前面的示例），这是一个警告，我们必须在串联之前检查变量是否存在，在您的示例中，它将是：

147:

$final_column[$key]=(isset($final_column[$key]))?$final_column[$key].=$value.'<br>':$value.' <br> ';

161:

$label_header=(isset($label_header))?$label_header.='<th>'.$value.'</th>':'<th>'.$value.'</th>';

1）如果您可以在SQL中进行排序/分组/聚合，那么就在SQL中执行，而不是在PHP中。SQL和rDBMS是为此而设计和优化的。

2） PHP没有多维数组，它们是分层的。

3）如果你不想在你的数组中有null，不要把它们放在中

4）如果您的数据中有结果集的主键，请将其用于数组密钥

while ($r=mysql_fetch_assoc($result)) {
    foreach($r as $key=>$val) {
      if ($val || $val===0 || $val===false) {
         $array[$r['Art']][$key]=$val;
      }
    }
}
