我需要一个数组,该数组将每个元素的键(由/
分隔)转换为子数组,并在新数组中以正确的格式分配数据。
可以有多个级别的嵌套,实际上从不超过10个,但这有待确定。
例如; 输入
$i_have_this = [
"Base/child" => [
[
"filename" => "child-1",
"last_modified" => "29/01/2020"
],
[
"filename" => "child-2",
"last_modified" => "29/01/2020"
],
[
"filename" => "child-3",
"last_modified" => "29/01/2020"
]
],
"Base/child/grandChild1" => [
[
"filename" => "grandChild1-1",
"last_modified" => "29/01/2020"
]
],
"Base/child/grandChild2" => [
[
"filename" => "grandChild2-1",
"last_modified" => "29/01/2020"
],
[
"filename" => "grandChild2-2",
"last_modified" => "29/01/2020"
],
[
"filename" => "grandChild2-3",
"last_modified" => "29/01/2020"
],
[
"filename" => "grandChild2-4",
"last_modified" => "29/01/2020"
],
[
"filename" => "grandChild2-5",
"last_modified" => "29/01/2020"
]
]
];
我想要输出
$want_this = [
'name' => 'Base',
'children' => [
[
'name' => 'child',
'children' => [
["name" => "child-1"],
["name" => "child-2"],
["name" => "child-3"],
[
"name" => "grandChild1",
"children" => [
["name" => "grandChild1-1"]
]
],
[
"name" => "grandChild2",
"children" => [
["name" => "grandChild2-1"],
["name" => "grandChild2-2"],
["name" => "grandChild2-3"],
["name" => "grandChild2-4"]
]
],
]
]
]
];
到目前为止,我有
foreach($i_have_this as $path => $value) {
$temp = &$want_this;
foreach (explode('/', $path) as $key) {
$temp = &$temp[$key];
}
$temp = $value;
}
但还不能完全解决问题。

我认为您可以像大多数人对数组使用“点”表示法一样对待它(例如Laravel)。只需替换“。”在您的情况下加上“ /”:
function unflatten($data) {
$output = [];
foreach ($data as $key => $value) {
$parts = explode('/', $key);
$nested = &$output;
while (count($parts) > 1) {
$nested = &$nested[array_shift($parts)];
if (!is_array($nested)) $nested = [];
}
$nested[array_shift($parts)] = $value;
}
return $output;
}
print_r(unflatten($i_have_this));
