Get images url from folder Filter only images from folder

Question

I use the code suggested here https://stackoverflow.com/a/18316453

This is what I have now.

<?php
$dir = "sliders/slides";
$images = array();
if (is_dir($dir))
{
if ($dh = opendir($dir))
 {
  while (($file = readdir($dh)) !== false)
  {
    if (!is_dir($dir.$file)) $images[] = $dir . '/' . $file;
  }
  closedir($dh);
 } 
}
echo json_encode($images);
?>

My result includes 2 extra items

sliders/slides/.
sliders/slides/..

which makes my slider having 2 extra blank slides

How can I filter the result to show only .jpg and .png files in order to remove /. and /.. be included in the results

I'm trying to create sliders that gets images from a folder

Thanks

Try something like this inside the while :

if ($file != "." && $file != ".." && !is_dir($file) {
    $images[] = $dir . '/' . $file;
}
