This is a follow up to a previous post http://sheldon.lendrum.co.nz/clean-dynamic-directory-listing-with-php_206/04/ that will Dynamically display the files in a set directory.

In this version the files can be ordered by the date that they were last modified. I will also explain how to order both Ascending and Descending by the date the file was created also.

Example Usages:

< ?php
	//  EAMPLE USAGE
	//  SHOWS THE 10 NEWEST .php FILES IN A UNORDERED LIST
	echo("
". direcotryList("10","./",".php","
","
\n") ."");

	//  SHOWS ALL JPG IMAGES AS THUMBNAILS
	echo(direcotryList("","./images/",".jpg","\n"));
?>

< ?php

	// DIRECTORY DISPLAY USING GLOB SORTNG BY LAST MIDIFIED FILE DATE.
	// IF ALL PERIMATORS ARE EMPTY WILL SCAN DEFAULT DIRECTORY
	// '$display' =>  AMOUNT OF RECORDS TO DISPLAY
	// '$path'    =>  PATH TO DIRECOTRY TO SCAN
	// '$ext'     =>  FILES EXT,  IF YOU WANT OT ECLUDE IT,  OR ONLY SCAN FOR ONE TYPE OF FILE
	// '$start'   =>  APPEND TO START OF OUTPUT LINE EG: '
' OR '
'
	// '$end'     =>  APPEND TO END OF OUTPUT LINE EG: '
' OR '\n' => DEFAULT '\n'
	function direcotryList($path = "./",$display = NULL, $ext = NULL, $start = NULL, $end = "\n"){
		$return = (int)0;
		$output = "";
		$ignore = array(".","..","thumbs.db");
		if(empty($display)){ $display = time() * 1000; }
		if(($count = count($files = glob($path ."*". $ext))) > 0){
			foreach($files as $v){
				$filemtime[] = filemtime($v);
			}
			array_multisort($filemtime, SORT_DESC, $files);
			foreach($files as $file){
				if($return < = $display){
					if(is_file($file) and !in_array($file, $ignore)){
						$output .= $start . $file . $end;
						$return++;
					}
				}
			}
		}
		return $output;
	}
?>

Alterations:

To order the directory by Creation time rather than the current Modified date Alter line 17 to filectime.

$filemtime[] = filectime($v);

Currently the output is orders Newest to Oldest, to reverse the Order, change the Constant in the array_multisort on line 19.

array_multisort($filemtime, SORT_DESC, $files);
