PHP数组数据添加问题：Volvo XC60归属错误修复求助

我有一个名为getPageContent的函数，用于列出版块、子版块及其中的资源。目前输出存在问题：Volvo XC60错误归属在Vauxhall子版块下，而非Volvo子版块。我纠结的代码行如下：

$sections[$section_index]->subsections[$section_index]->subcontent[] = $subContent;

预期层级 #

• Cars (Section)
  • Car Guide (Section resource)
  • Vauxhall (Sub Section)
    • Vauxhall Corsa (sub section resource)
    • Vauxhall Astra (sub section resource)
  • Volvo (Sub Section)
    • Volvo XC60 (sub section resource)

函数代码 #

public function getPageContent($id)
{
    $sections = $this->Pages_Section->get($id);
    $groupIds = [1,2,3,4];

    foreach ($sections as $section_index => $section) {
        for ($y = 0; $y <= 5; $y++) {
            $sections[$section_index]->content[$y] = [];
        }

        $subSections = $this->Pages_Section->order_by('position')->getwhere(['sections_parent_id' => $section->id]);
        if (is_array($subSections) && $subSections !== []) {
            foreach ($subSections as $subSection) {
                $sections[$section_index]->subsections[] = $subSection;
                $subSectionContents = $this->Pages_Sections_Resource->getbysectiongroups($subSection->id, $groupIds);
                foreach ($subSectionContents as $subIndex => $subContent) {
                    if ((int) $subContent->pages_sections_id === (int) $subSection->id) {
                       $sections[$section_index]->subsections[$section_index]->subcontent[] = $subContent;
                    }
                }
            }
        }

        $contents = $this->Pages_Sections_Resource->getbysectiongroups($section->id, $groupIds, $type);
        foreach ($contents as $content) {
            if ($content->year >= 0 && $content->year <= $programmeYear) {
                $sections[$section_index]->content[$content->year][] = $content;
            }
        }
    }

    return $sections;
}

当前$sections返回的数组 #
