fileatime
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)
filectime — Renvoie la date de dernier accès à un inode
Description
int filectime
( string
$filename
)Renvoie la date de dernier accès à un inode d'un fichier.
Liste de paramètres
-
filename -
Chemin vers le fichier.
Valeurs de retour
Renvoie la date à laquelle l'inode a été accédé pour
la dernière fois ou FALSE si une erreur survient. L'heure
est retournée sous la forme d'un timestamp Unix.
Exemples
Exemple #1 Exemple avec filectime()
<?php
// Affiche : somefile.txt a été modifié le : December 29 2002 22:16:23.
$filename = 'somefile.txt';
if (file_exists($filename)) {
echo "$filename a été modifié le : " . date("F d Y H:i:s.", filectime($filename));
}
?>
Erreurs / Exceptions
En cas d'échec, une alerte de type E_WARNING sera émise.
Notes
Note:
Sur la plupart des serveurs UNIX, un fichier est considéré comme modifié si les données de son inode sont modifiées. C'est-à-dire lorsque les permissions (utilisateur, groupe ou autre) ont été modifiées. Voyez aussi filemtime() (que vous pourrez utiliser lorsque vous créerez des indications telles que "Dernière modification : " sur les pages web) et fileatime().
Note:
Notez aussi que sur certains systèmes UNIX, le ctime d'un fichier texte est considéré comme sa date de création. Cela est faux ! Il n'y a pas de date de création de fichier sous la plupart des systèmes UNIX.
Note:
Notez que la précision temporelle peut varier selon le système de fichiers utilisé.
Note: Les résultats de cette fonction sont mis en cache. Voyez la fonction clearstatcache() pour plus de détails.
Astuce
Depuis PHP 5.0.0, cette fonction peut aussi être utilisée avec quelques protocoles url. Lisez Liste des protocoles et des gestionnaires supportés pour connaître les protocoles supportant la famille de fonctionnalités de stat().

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".

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.

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

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 />';
}
?>

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

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

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

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 />';
}
?>

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.
