php readdir - how can you list the files by date?
The below script returns the list of all the files in the specified directory by the default in reverse alphabetical order.
How can I list the contents of the directory by date created?
Is there a directory listing default in debian Ubuntu linux?
Or how can I get the file information from the server i.e. the date to build an array to later be sorted by the stored date? How would I build that php array?
Thanks

<?php
$directory = "images/original";
$handler = opendir($directory);
while (false !== ($file = readdir($handler))) {
if ($file != "." && $file != "..") {
echo '<img class="libraryImage" src="' . $directory . '/' . $file . '" alt="' . $file . '" />';
}
}
closedir($handler);
?>
</div>

Thanks this generally works. It isn't sorting some of the files though. Here are the results from the SortByDate, server directory image, and my altered code of your functions. Any idea what I'm doing wrong?
function LoadFiles($dir) {
$Files = array();
$handler = opendir($dir);
if (!$handler)
die('Cannot list files for ' . $dir);
while ($Filename = readdir($handler)) {
if ($Filename == '.' || $Filename == '..')
continue;
$LastModified = filemtime($dir . $Filename);
$Files[] = array($dir . $Filename, $LastModified);
}
return $Files;
}
function DateCmp($a, $b) {
return ($a[1] < $b[1]) ? -1 : 0;
}
function SortByDate(&$Files) {
usort($Files, 'DateCmp');
}
$Files = LoadFiles('images/original/');
SortByDate($Files);
foreach($Files as $source)
echo '<img class="libraryImage" src="/' . $source[0] . '" alt="' . date("F d Y H:i:s", $source[1]) . '" />';
?>
