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
(PHP 4, PHP 5, PHP 7)
filectime — Gets inode change time of file
설명
int filectime
( string
$filename
)Gets the inode change time of a file.
인수
-
filename -
Path to the file.
반환값
Returns the time the file was last changed, 실패 시 FALSE를 반환합니다.
The time is returned as a Unix timestamp.
예제
Example #1 A filectime() example
<?php
// outputs e.g. 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));
}
?>
오류/예외
실패 시, E_WARNING이 발생합니다.
주의
Note:
Note: In most Unix filesystems, a file is considered changed when its inode data is changed; that is, when the permissions, owner, group, or other metadata from the inode is updated. See also filemtime() (which is what you want to use when you want to create "Last Modified" footers on web pages) and fileatime().
Note:
Note also that in some Unix texts the ctime of a file is referred to as being the creation time of the file. This is wrong. There is no creation time for Unix files in most Unix filesystems.
Note:
시간 정밀도는 각각 파일 시스템에 따라 다를 수 있습니다.
Note: 이 함수의 결과는 캐시에 저장합니다. 자세한 설명은 clearstatcache()를 참고하십시오.
Tip
PHP 5.0.0부터 이 함수는 몇몇 URL 래퍼를 사용할 수 있습니다. 기능적으로 stat() 패밀리를 지원하는 래퍼 목록은 Supported Protocols and Wrappers를 참고하십시오.

If you need file creation time on Mac OS X:
<?php
if ($handle = popen('stat -f %B ' . escapeshellarg($filename), 'r')) {
$btime = trim(fread($handle, 100));
echo strftime("btime: %Y.%m.%d %H:%M:%S\n", $btime);
pclose($handle);
}
?>

Under Windows you can use fileatime() instead of filectime().

You should avoid feeding the function files without a path. This applies for filemtime() and possibly fileatime() as well. If you omit the path the command will fail with the warning "filectime(): stat failed for filename.php".

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.

Filemtime seems to return the date of the EARLIEST modified file inside a folder, so this is a recursive function to return the date of the LAST (most recently) modified file inside a folder.
<?php
// Only take into account those files whose extensions you want to show.
$allowedExtensions = array(
'zip',
'rar',
'pdf',
'txt'
);
function filemtime_r($path)
{
global $allowedExtensions;
if (!file_exists($path))
return 0;
$extension = end(explode(".", $path));
if (is_file($path) && in_array($extension, $allowedExtensions))
return filemtime($path);
$ret = 0;
foreach (glob($path."/*") as $fn)
{
if (filemtime_r($fn) > $ret)
$ret = filemtime_r($fn);
// This will return a timestamp, you will have to use date().
}
return $ret;
}
?>

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

Note that on Windows systems, filectime will show the file creation time, as there is no such thing as "change time" in Windows.

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.
