fileatime
This is a modification of simraLIAS at mac dot com's code.
Modification dates should not be used for keys in an array when sorting by date because there is no guarantee that all files will have different dates. Collisions resulting in files missing from the list could be possible. A better way is to use the filename as the key (guaranteed to not be collisions)
<?php
foreach (glob("../downloads/*") as $path) { //configure path
$docs[$path] = filectime($path);
} asort($docs); // sort by value, preserving keys
foreach ($docs as $path => $timestamp) {
print date("d. M. Y: ", $timestamp);
print '<a href="'. $path .'">'. basename($path) .'</a><br />';
}
?>
filectime
(PHP 4, PHP 5)
filectime — 取得文件的 inode 修改时间
说明
int filectime
( string $filename
)
返回文件上次 inode 被修改的时间，如果出错则返回 FALSE。时间以 Unix 时间戳的方式返回。
注意：在大多数 Unix 文件系统中，当一个文件的 inode 数据被改变时则该文件被认为是修改了。也就是说，当文件的权限，所有者，所有组或其它 inode 中的元数据被更新时。参见 filemtime()（这才是你想用于在 Web 页面中建立“最后更新时间”脚注的函数）和 fileatime()。
注意某些 Unix 说明文本中把 ctime 说成是该文件建立的时间，这是错的。在大多数 Unix 文件系统中没有 Unix 文件的建立时间。
Note: 本函数的结果会被缓存。更多信息参见 clearstatcache()。
Tip
自 PHP 5.0.0 起本函数也可被某些 URL wrapper 使用。参考支持的协议／封装协议列表 来看哪些 wrapper 支持 stat() 系列函数的功能。
Example#1 一个 fileatime() 的例子
<?php
// 输出类似：somefile.txt was last changed: December 29 2002 22:16:23.
$filename = 'somefile.txt';
if (file_exists($filename)) {
echo "$filename was last changed: " . date("F d Y H:i:s.", filectime($filename));
}
?>
参见 filemtime()。

This is another way to get a list of files ordered by upload time:
<?php
foreach (glob("../downloads/*") as $path) { //configure path
$docs[filectime($path)] = $path;
} ksort($docs); // sort by key (timestamp)
foreach ($docs as $timestamp => $path) {
print date("d. M. Y: ", $timestamp);
print '<a href="'. $path .'">'. basename($path) .'</a><br />';
}
?>

filectime running on windows reading a file from a samba share, will still show the last modified date.

Line 37 of the code above has an error.
echo "File name: $file - Date Added: $date. <br/>"";
There is an extra " after the <br/> that needs to be deleted in order for this code to work.

This method gets all the files in a directory, and echoes them in the order of the date they were added (by ftp or whatever).
<?PHP
function dirList ($directory, $sortOrder){
//Get each file and add its details to two arrays
$results = array();
$handler = opendir($directory);
while ($file = readdir($handler)) {
if ($file != '.' && $file != '..' && $file != "robots.txt" && $file != ".htaccess"){
$currentModified = filectime($directory."/".$file);
$file_names[] = $file;
$file_dates[] = $currentModified;
}
}
closedir($handler);
//Sort the date array by preferred order
if ($sortOrder == "newestFirst"){
arsort($file_dates);
}else{
asort($file_dates);
}
//Match file_names array to file_dates array
$file_names_Array = array_keys($file_dates);
foreach ($file_names_Array as $idx => $name) $name=$file_names[$name];
$file_dates = array_merge($file_dates);
$i = 0;
//Loop through dates array and then echo the list
foreach ($file_dates as $file_dates){
$date = $file_dates;
$j = $file_names_Array[$i];
$file = $file_names[$j];
$i++;
echo "File name: $file - Date Added: $date. <br/>"";
}
}
?>
I hope this is useful to somebody.

filectime doesn't seem to be working properly on Win32 systems (it seems to return the creation time). Try using filemtime if you have problems.

If you use filectime with a symbolic link, you will get the change time of the file actually linked to. To get informations about the link self, use lstat.
