Is There A Way To glob() Only Files?

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).

Solution

  • 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.
