我有一个数组,例如:
$tree = array(
'folder_1' => array(
'folder_1_1',
'folder_1_2' => array(
'folder_1_2_1',
'folder_1_2_2'
),
'folder_1_3'
),
'folder_2' => array(
'folder_2_1' => array(
'folder_2_1_1' => array(
'folder_2_1_1_1',
'folder_2_1_1_2'
)
),
)
);
我正在尝试构建一系列路径:
$paths = array(
'folder_1',
'folder_1/folder_1_1',
'folder_1/folder_1_2',
'folder_1/folder_1_2/folder_1_2_1',
'folder_1/folder_1_2/folder_1_2_2',
'folder_2',
'folder_2/folder_2_1',
...
);
我似乎无法找到实现这一目标的方法。我遇到的问题是文件夹名称可以是数组键,也可以是数组元素。
这是我到目前为止所做的,但我还没有找到解决方案......
$paths = transform_tree_to_paths($trees);
function transform_tree_to_paths($trees, $current_path = '', $paths = array())
{
if (is_array($trees)) {
foreach ($trees as $tree => $children) {
$current_path .= $tree . '/';
return transform_tree_to_paths($children, $current_path, $paths);
}
$paths[] = $current_path;
$current_path = '';
} else {
$paths[] = $trees;
}
return $paths;
}
