PHP PharData: build .tar archive from directory, with exclusions - php

Question

TLDR version:
how to utilize PharData::buildFromIterator in order to build .tar archive from /path/to/project/, but excluding a list of files, like /path/to/project/file0.txt, /path/to/project/file1.txt, /path/to/project/file2.txt?
Longer version, what-have-I-tried included:
In order to build .tar archive from dir path, I tried with the simple PharData::buildFromDirectory method which has a second, optional argument which... kind of... does exact opposite of what I need
"pcre regular expression [...] Only file paths matching the regular expression will be included in the archive"
. So I guess, the only option left is to utilize PharData::buildFromIterator which has a simple usage example:
$phar->buildFromIterator(
new RecursiveIteratorIterator(
new RecursiveDirectoryIterator('/path/to/project', FilesystemIterator::SKIP_DOTS)
),
'/path/to/project'
);
This example may be a starting point but from here I do not know how to exclude a list of files from iterator?

In case someone finds this question useful, I shall post an answer since I have figured it out how to do it, with solutions to similar problem found here, thanks to user Levi Morrison.
(tested OK on Windows filesystem, assumes __DIR__ is the directory where it runs)
$exclude = ['file0.txt', 'file1.txt', 'file2.txt'];
/**
* #param SplFileInfo $file
* #param mixed $key
* #param RecursiveCallbackFilterIterator $iterator
* #return bool True if you need to recurse or if the item is acceptable
*/
$filter = function ($file, $key, $iterator) use ($exclude) {
foreach($exclude as $excludefilename){
if(
strcmp(__DIR__ . DIRECTORY_SEPARATOR . $excludefilename, $file) === 0
) return false;
}
return true;
};
$innerIterator = new RecursiveDirectoryIterator(
__DIR__,
RecursiveDirectoryIterator::SKIP_DOTS
);
$iterator = new RecursiveIteratorIterator(
new RecursiveCallbackFilterIterator($innerIterator, $filter)
);
$phar = new PharData('project.tar');
$phar->buildFromIterator($iterator, __DIR__);
