Question

I have an empty folder called my_folder:

$mas = glob("my_folder/*");
var_dump($mas);

If in my_folder I have files, the result is an array, but if my_folder is empty, the result is false.

Why is the result false and not an empty array()?

Answer 1

• Most likely you don’t have permissions on my_folder.

• Also it could be because (from PHP manual):

On some systems it is impossible to distinguish between empty match and an error.

If the latter is your case i suggest you to fall back to “classic” way to do that:

while (false !== ($entry = readdir($handle))) {
        echo "$entry\n";
}

Using:

opendir(), readdir(), closedir()
