Question

here my code-

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

wher I run this code unnecessary dots(.) are coming.
output image-3.jpgimage-4.jpgimage-1.jpgimage-2.jpgimage-5.jpg... why 3 dots are coming at the last??

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
