get all the images from a folder in php

Question

I am using WordPress. I have an image folder like mytheme/images/myimages.

I want to retrieve all the images name from the folder myimages<

Answer 1

$dir = "mytheme/images/myimages";
$dh  = opendir($dir);
while (false !== ($filename = readdir($dh))) {
    $files[] = $filename;
}
$images=preg_grep ('/\.jpg$/i', $files);

Very fast because you only scan the needed directory.
