I am trying to use the readdir() function to read all the content of a folder so I can display the images like in the code below. when i use this function it always gives me a " . " and a " .. "   How do I not include them in the results?
thanks for any help with this


B
$dir = opendir("photos/food");
while (($file = readdir($dir)) !== false)
  {
echo   "<a href=\"photos/food/" . $file . "\"" . "rel=\"lightbox[vacation1]\" title=\"\">
            <img src=\"photos/food/" . $file . "\"" . "alt=\"\" height=\"50px\" width=\"50px\"/>
          </a>";
  }

dot and dotdot are always returned  representing the current folder and parent folder respectively.

$dir = opendir("photos/food");
while (($file = readdir($dir)) !== false)
  if ($file<>'.' && $file<>'..')
    {
      echo   "<a href=\"photos/food/" . $file . "\"" . "rel=\"lightbox[vacation1]\" title=\"\">
            <img src=\"photos/food/" . $file . "\"" . "alt=\"\" height=\"50px\" width=\"50px\"/>
          </a>";
    }

if ($file<>'.' && $file<>'..')

is
  if  ( $file    is not equal to   '.'    and     $file     is not equal to     '..'  )
