Is There A Way To glob() Only Files?

Question

I know that glob can look for all files or only all directories inside a folder :

echo "All files:\n"; $all = glob("/*"); var_dump($all);  echo "Only directories\n"; $dirs = glob("/*", GLOB_ONLYDIR); var_dump($dirs); 

But I didn't found something to find only files in a single line efficiently.

$files = array_diff(glob("/*"), glob("/*", GLOB_ONLYDIR)); 

Works well but reads directory twice (even if there are some optimizations that make the second browsing quicker).

I finally found a solution :

echo "Only files\n"; $files = array_filter(glob("/*"), 'is_file'); var_dump($files); 

But take care, array_filter will preserve numeric keys : use array_values if you need to reindex the array.
