排序一個PHP腳本的縮略圖

的結果我發現這是拍攝圖像的目錄，並創建縮略圖淨以下PHP腳本。這部分工作很好，期待我注意到排序關閉。最好的我可以告訴的是它的使用的文件名，我想使用的創建日期，因爲我分類從安全的相機創建的圖像的目錄。排序一個PHP腳本的縮略圖

任何輸入和方向的位（OK，很多）將是巨大的，因爲我沒有很多的PHP經驗，但可以避開一些。再次

感謝您的幫助！

我已經添加了非常骯髒的排序方式（效率不高）。以下行更改爲SORT_DESC或SORT_ASC代碼降序排序或上升。

arraySortByColumn($exifData, 'time', SORT_DESC);

你添加了排序功能的腳本：

<html><head><title>Snapshots</title></head>

<?php 
$folder = '.'; 
$dir = getcwd(); 
DirStat($folder, 0); 
chdir($dir); 
$FolderSize = ByteSize($FolderSize); 
$FileCount=$FileCount-2; 
?> 

<h2 align=center><?php echo date('m/d/Y H:i:s') ." - $FileCount Snapshots - $FolderSize";?></h4> 

<?php 

$imagens=''; 
$exifData = array(); 
$dn = opendir('.'); 
while (false !== ($file = readdir($dn))) { 
if ($file == '.' || $file =='..' || $file =='index.php' || $file =='Thumbs.db'){ 
     //print "<a href=$file>$file</a><br>"; 
}else{ 
     if (is_dir($file)){ 
       print "<img src='/imagens/diretorio.png'>&nbsp;<a href='$file?dir=dirname(__FILE__)'>$file</a><br>"; 
     }else{ 
       $tamanho = filesize($file); 
       $datetime = @exif_read_data($file); 
       $m = 'bytes'; // 
       if ($tamanho>1024) { 
         $tamanho=round($tamanho/1024,2); 
         $m = 'KB'; 
       } elseif($tamanho > 1024*1024){ 
         $tamanho = round(($tamanho/1024)/1024,2);

closedir($dn); 
//change to SORT_DESC or SORT_ASC
