I have an array containing full paths of files. Like this:
[0] => "dir1/dir2/dir3/file.ext"
[1] => "dir1/dir2/dir3/file2.ext"
[2] => "dir1/dir2/dir3/file3.ext"
[3] => "dir2/dir4/dir5/file.ext"
I need to parse it and get a multidimensional array, something like this:
[dir1] => [dir2] => [dir3] => file.ext
=> file2.ext
=> file3.ext
[dir2] => [dir4] => [dir5] => file.ext
Any ideas? Must work with various depth of the structure.
To build off of @J. Bruni's answer, the code that you need is the following:
function parse_paths_of_files($array)
{
rsort($array);
$result = array();
foreach ($array as $item) {
$parts = explode('/', $item);
$current = &$result;
for ($i = 1, $max = count($parts); $i < $max; $i++) {
if (!isset($current[$parts[$i - 1]])) {
$current[$parts[$i - 1]] = array();
}
$current = &$current[$parts[$i - 1]];
}
$last = end($parts);
if (!isset($current[$last]) && $last) {
// Don't add a folder name as an element if that folder has items
$current[] = end($parts);
}
}
return $result;
}
J Bruni's answer is dodgy because it assumed values are there that aren't, resulting in a lot of PHP undefined index errors.
This version also prevents a folder name being added to the list if the folder already has an entry to prevent:
$result = [
0 => folder_name
folder_name => [
...
]
]
I've done your homework! :-)
Code:
<?php
function parse_paths_of_files($array)
{
$result = array();
foreach ($array as $item)
{
$parts = explode('/', $item);
$current = &$result;
for ($i = 1, $max = count($parts); $i < $max; $i++)
{
if (!isset($current[$parts[$i-1]]))
{
$current[$parts[$i-1]] = array();
}
$current = &$current[$parts[$i-1]];
}
$current[] = $parts[$i];
}
return $result;
}
$test = array(
"dir1/dir2/dir3/file.ext",
"dir1/dir2/dir3/file2.ext",
"dir1/dir2/dir3/file3.ext",
"dir2/dir4/dir5/file.ext"
);
print_r(parse_paths_of_files($test));
?>
