List all files in a directory ,extra information is coming

Question

here my code-

if ($handle = opendir(\'banner/\')) {    
    while (false !== ($file = readdir($handle))) { 
        echo \"$file\"; 
    }     
    closedir($han         


        

Answer 1

Because . is the current directory and .. is the parent directory.

They are always exists.

If you need to exclude them - just add

if ($file != '.' && $file != '..')

right before echo

Answer 2

It's because there are items in your directory which you don't see... one of them is . and represents the current directory, and the other is .. and represents the directory above the current one. You need to filter these out of any readdir results.
