with paging.
i am getting images from directory by giving path .
how would i improve it .
<?php

$dirname = 'entertainment/img'; //directory in which images are located.
$dh = opendir($dirname);
while ( ! is_bool( $file = readdir( $dh )) ) {
$dir = ( is_dir($file) ) ? $dir = 'true' : $dir = 'false';
if($dir=='true') { }else{ if( $file=='Thumbs.db'){ continue;} $ImagesStorageArray[] = $file ; $totalImages++;}
}//end while
echo 'Total Images :: '.$totalImages.'<br>';
// number of images in folder.
$total_items = $totalImages;
//images perpage
$perPage = 8;
//current page number
$pageNum = ($_GET[pageNum]=='')? 1 : $_GET[pageNum]; #set default page number.
$cur = ceil( $per_page/ $pageNum) + 1; // Current page number
//start position(key) in the array
