Fix problem with braces in template:
<?php
class GlobStreamWrapper
{
private
$generator;

protected function
createGenerator(array $paths): Generator
{
return yield from
$paths;
}

public function
dir_opendir(string $pattern, int $options = 0): bool
{
$pattern = substr($pattern, 7); // crop 'glob://' prefix
$pattern = str_replace(['\\', '/'], DIRECTORY_SEPARATOR, $pattern);
$paths = (array) glob($pattern, GLOB_BRACE | GLOB_NOSORT);
$this->generator = $this->createGenerator($paths);
return
$this->generator->valid();
}

public function
dir_readdir(): string
{
$path = $this->generator->current() ?: '';
$this->generator->next();
return
$path;
}

public function
dir_rewinddir(): bool
{
$this->generator->rewind();
return
$this->generator->valid();
}

public function
dir_closedir(): bool
{
$this->generator = null;
return
true;
}
}
?>
Replace glob wrapper:
<?php
stream_wrapper_unregister
('glob');
stream_wrapper_register('glob', 'GlobStreamWrapper');
?>
Example:
<?php
$iterator
= new GlobIterator(__DIR__ . '/{application,system}/src/*.php');
while (
$iterator->valid()) {
echo
$iterator->current()->getFilename() . '</br>';
$iterator->next();
}
?>

GlobIterator doesn’t have a way to support GLOB_BRACE!

<?php
$iterator
= new GlobIterator(getcwd. '/*.{php,txt}'); // generate an empty array
?>
