Question

我今天一直在处理一些代码，我遇到了一个小的多维数组问题。首先，阅读我编写的一些代码以便更好地了解问题本身可能很方便：

public function treeLeaves(array $elements, $parent = 0) {

$branch = array();

foreach($elements as $element) {

    $leaf = array('pageid'      => $element['pageid'],
                  'page_parent' => $element['page_parent'],
                  'label'       => ucfirst($element['page_print'][0]['print_title']),
                  'uri'         => $element['page_alias']);

    if($element['page_parent'] == $parent) {
        $children = $this->treeLeaves($elements, $leaf['pageid']);
        if($children) {
            foreach($children as $key => $child) {
                $leaf['pages'][] = $children[$key];
            }
        }
        $branch[] = $leaf;
    }
}

return $branch; }

出于某种原因，我无法弄清楚如何将父URI别名粘贴到所有单独的子URI上。我想要的结果应该是这样的：http://pastebin.com/Eh9ExBjG

我希望有些高手可以帮助我。我一直在尝试这么多不同的东西，但不能解决这个问题，即使我觉得它相对容易解决。

有些简化，但我想你会明白这个想法：

function treeLeaves($elements, $parent = 0, $baseUri = '/index') {
    $branch = array();
    foreach($elements as $element) {
        if ($element['page_parent'] == $parent) {
            $leaf = array(
                'uri'    => $baseUri . '/' . $element['page_alias'];
            );
            $leaf['pages'] = treeLeaves($elements, $element['pageid'], $leaf['uri']);
            $branch[] = $leaf;
        }
    }
    return $branch;
}
