PHP：包含来自未知文件夹的已知文件名

Question

I am making a website the tech-tree of a game a friend is making. The tech-three itself is just a list of links going from one page to the other. The variables for each page are stored in a php file e.g.: mining.php. I don't want to have a massive list of files all in one folder. So far all I've managed to do is sort them into just the first branches of the tree with this:

$path = glob('tree/*/'.$page.'.php');
if ($path[0]) {
    include $path[0];

Ideally I want to be able to access the file from anywhere in the tree.
e.g.: The file mining.php would be at tree/strength/mining.php. And the file pickaxe.php would be at tree/strength/mining/pickaxe.php. But I would be able to include either one with the same include. What could i use to get my known filename from any folder or subfolder in the tree folder.

Answer 1

I worked out an answer for myself (it took me a few hours but this will make it easier to sort through the hundred of files that i will eventually have):

$count = 0;
$path = 'tree/*/';
$file = glob($path.$page.'.php');
while ((strpos($file[0], $page) == false) and ($count != 10)) {
    $file = glob($path.$page.'.php');
    $path .= '*/';
    $count++;
}
if (strpos($file[0], $page) == true) {
    include $file[0];

Just make sure you know how many folders you have and make (count == #) higher.
