PHP - File Handling

You want to retrieve only the regular files (not directories) from the directory reports. Which PHP code snippet correctly achieves this?

A$files = array_filter(scandir('reports'), function($f) { return is_file('reports/' . $f); });

B$files = scandir('reports'); foreach ($files as $f) { if (is_dir('reports/' . $f)) echo $f; }

C$files = scandir('reports'); $files = array_filter($files, 'is_dir');

D$files = scandir('reports'); foreach ($files as $f) { echo $f; }

$files = array_filter(scandir('reports'), function($f) { return is_file('reports/' . $f); }); uses array_filter with is_file() correctly to get only files.
Final Answer:
