你好，我想生成类别树，如n级别的wordpress。
这是我的示例数组。

现在父类别和子类别关系介于ParentCat字段和自动字段之间。
现在我尝试了这段代码
foreach($tree as $el){
$thisref = &$refs->{$el->Auto};
foreach($el as $k => $v){
@$thisref->{$k} = $v;
}
if($el->ParentCat == 0){
$reportTree->{$el->Auto} = &$thisref;
}
else{
$refs->{$el->ParentCat}->children->{$el->Auto} = &$thisref;
}
$reportTree;
}
我在数组中有800个元素，并尝试使用上面的代码生成树。 但单个元素在数组中插入100次。但它应该只插入一次。
父子关系 例如 在这里，我从数组中获取2个元素。
[1] => stdClass Object
(
[Id] => 12878
[CoaName] => Income
[CompId] => 1
[ParentCat] => 0
[Auto] => 1
[flgActive] => 1
)
[2] => stdClass Object
(
[CoaName] => I · ROOM REVENUE
[ParentCat] => 1
[Auto] => 23
[flgActive] => 1
)
现在第二个元素的ParentCat值为1和 第一个元素具有Auto 1，因此第一个元素是第二个元素的父元素。 那么请你建议我怎么做。 谢谢

如果我理解正确 - 以下内容应该有效：
首先通过你的id键分配数组（根据你的php示例，它不总是一个id - 但我认为这是一个复制错误）
$arrTreeById = array();
$arrTree = array();
foreach($arrTree AS $objItem)
{
$arrTreeById[$objItem->Id] = $objItem;
$objItem->arrChilds = array();
}
在完成该作业后，您只需将孩子添加到父母
foreach($arrTreeById AS $objItem)
{
if (isset($arrTree[$objItem->ParentCat])) $arrTree[$objItem->ParentCat]->arrChilds[] = $objItem;
if ($objItem->ParentCat == 0) $intStartingKey = $objItem->Id;
}
print_r($arrTree[$intStartingKey]);
或者我错过了什么？

我已经为这个函数开发了一个函数来传递这个函数
function buildArrayTree($items){
$ref = array(); // track references
$Childrens = array(); // new array
// menu reference since can't push directly later
foreach($original = &$items as $item)
{
if($item->ParentCat == 0)
{
// add item
$Childrens[$item->Auto] = array($item);
// track item reference
$ref[$item->Auto] = &$Childrens[$item->Auto];
}
else
{
// index of Childrens array
$count = isset($ref[$item->ParentCat]['Childrens'])
? count($ref[$item->ParentCat]['Childrens']) : 0;
// parent already there? else move to back
if(isset($ref[$item->ParentCat]))
{
// set item under proper Childrens array item
$ref[$item->ParentCat]['Childrens'][] = array($item);
// track reference to new item
$ref[$item->Auto] = &$ref[$item->ParentCat]['Childrens'][$count];
}
else
{
// if parent isn't there, add to end of array and we'll get to it later
array_push($original, $item);
}
}
}
return $Childrens;
}
