public count(): int
/* Inherited methods */
public FilesystemIterator::__construct(string $path, int $flags = FilesystemIterator::KEY_AS_PATHNAME | FilesystemIterator::CURRENT_AS_FILEINFO | FilesystemIterator::SKIP_DOTS)

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();
}
?>
