Get section name by key name of an ini file in php - php

Question

I have an ini file which looks like this:
[236a4e392b6dd0a8409bb91c664ab6468be32555]
76561197961658420=DaRoL
76561197962180350=Spow
76561197962376928=Kolma
[efd3dd758092ad90e35fb634a203c41b90da6333]
76561197964385070=Kelininkas
76561199641652847=Kelininkas
How is it possible in PHP to return the section name by searching with a key name (or optional key value).
e.g. 76561197964385070 -> efd3dd758092ad90e35fb634a203c41b90da6333 and optional
Kelininkas -> efd3dd758092ad90e35fb634a203c41b90da6333
I imported the ini file into an array and I'm able to find the key and item.
But not the key name of the superordinate key.
<?php
header('Content-type: text/plain');
$ini_array = (parse_ini_file("BannedHWs.ini",true));
$steamid="76561197962180330";
function find($item, $key)
{
global $steamid;
if ($key == $steamid)
echo "$key FOUND $item\n";
}
array_walk_recursive($ini_array, 'find');
echo "\n";
print_r ($ini_array); // SHOW ARRAY
?>
Result:
76561197962180330 FOUND Spow
Array
(
[236a4e392b6dd0a8409bb91c664ab6468be32d15] => Array
(
[76561197961658460] => DaRoL
[76561197962180330] => Spow
[76561197962376938] => Kolma
)
[efd3dd758092ad90e35fb634a203c41b90da6895] => Array
(
[76561197964385060] => Kelininkas
[76561199641652827] => Kelininkas
)
)
Thanks in advance

If you are on a linux machine, this might help you. This is not a solution, but a path where you can go further.
$ cat some_config_ini.txt
[efd3dd758092ad90e35fb634a203c41b90da6333]
76561197964385070=Kelininkas
76561199641652847=Kelininkas
$ cat some_config_ini.txt | grep Kelininkas -B 1 | head -1
[efd3dd758092ad90e35fb634a203c41b90da6333]
Above commands will not work with your original file.
$ cat som_config_ini.txt | grep Spow -B 1 | head -1
76561197961658420=DaRoL
However if you know know the key&values under a block, you can try this.
$ cat som_config_ini.txt | grep Spow -B 2 | head -1
[236a4e392b6dd0a8409bb91c664ab6468be32555]
$ cat som_config_ini.txt | grep Kolma -B 3 | head -1
[236a4e392b6dd0a8409bb91c664ab6468be32555]
Be aware of the arguments passed to grep [-B 1/2/3].
I can offer ruby&python solutions if you prefer.

Found my own solution:
<?php
header('Content-type: text/plain');
$ini_array = (parse_ini_file("BannedHWs.ini",true));
$steamid="76561199641652827";
function findID(array $array, $path = null) {
global $steamid;
foreach ($array as $k => $v) {
if (!is_array($v)) {
if ($k == $steamid){
echo "HWID: $path\n";
}
}
else {
findID($v, $path.$k);
}
}
}
findID($ini_array);
//echo "\n";
//print_r ($ini_array); // SHOW ARRAY
?>
Based on:
get parent array name after array_walk_recursive function
