opendir/image load help

[PlagueInfected]

I'm trying to use PHP to open a certain dir path and to get the filename of jpg, png and gif images than echo it into an html code to be viewed.

 

here's what I got, I can't get my images in html to preview...

 

<?php
$dir = "/_img/_v9/portfolio";

// Open a known directory, and proceed to read its contents
if (is_dir($dir)) {
    if ($dh = opendir($dir)) {
    if (preg_match("/[^.\/].+\.(jpg|png|gif)$/",$dir,$file)) {
        while (($file = readdir($dh)) !== false) {
            echo "<a href=\"../_img/portfolio/$file\" rel=\"lightbox\"><img src=\"../_img/portfolio/thumbnails/$file\" alt=\"\" /></a>";
        }
	}
        closedir($dh);
    }
}
?>

[trq]

foreach (glob('/_img/_v9/portfolio/.{jpg,png,gif}', GLOB_BRACE) as $file) {
  $file = basename($file);
  echo "<a href=\"../_img/portfolio/$file\" rel=\"lightbox\"><img src=\"../_img/portfolio/thumbnails/$file\" alt=\"\" /></a>";
}

just tried that, here is how i coded it

 

$dir = "/_img/_v9/portfolio";

// Open a known directory, and proceed to read its contents
if (is_dir($dir)) {
    if ($dh = opendir($dir)) {
      foreach (glob('/_img/_v9/portfolio/.{jpg,png,gif}', GLOB_BRACE) as $file) {
    $file = basename($file);
       echo "<a href=\"../_img/portfolio/$file\" rel=\"lightbox\"><img src=\"../_img/portfolio/thumbnails/$file\" alt=\"\" /></a>";
       }
        closedir($dh);
    }
}

 

it's still blank when viewing

My entire piece of code is all you need.
