实现代码：
sonlist 查询的元数据 使用&引用方法实现
// 创建基于主键的数组引用
$refer = array();
foreach ($sonlist as $key => $data) {
$refer[$data["years"]][$data["month"]][] = &$sonlist[$key];
} public function getFormatMenus($map = [], $field = '*')
{
$list = $this->field($field)->where($map)->select()->order('sort asc')->toArray();
return $list ? $list : [];
}
public function listToTree(array $list)
{
$tree = array();
$pk = 'id';
$pid = 'pid';
$root = 0;
$child = 'children';
if (is_array($list)) {
// 创建基于主键的数组引用
$refer = array();
foreach ($list as $key => $data) {
$refer[$data[$pk]] = &$list[$key];
}
foreach ($list as $key => $data) {
// 判断是否存在parent
$parentId = $data[$pid];
if ($root == $parentId) {
$tree[] = &$list[$key];
} else {
if (isset($refer[$parentId])) {
$parent = &$refer[$parentId];
$parent['childs'][] = $data['id'];
$parent[$child][] = &$list[$key];
}
}
}
}
return $tree;
}
