fileatime
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".
filectime
(PHP 4, PHP 5)
filectime — Gets inode change time of file
Descrierea
int filectime
( string $filename
)
Gets the inode change time of a file.
Parametri
- filename
-
Path to the file.
Valorile întoarse
Returns the time the file was last changed, sau FALSE în cazul eșecului. The time is returned as a Unix timestamp.
Exemple
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));
}
?>
Erori/Excepții
În cazul eșecului este emis un E_WARNING.
Note
Notă:
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().
Notă:
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.
Notă:
Observați că rezoluția timpului poate să difere de la un sistem de fișiere la altul.
Notă: Rezultatele acestei funcții sunt stocate în cache. Accesați clearstatcache() pentru mai multe detalii.
Sfat
Începând cu PHP 5.0.0 această funcție poate fi utilizată de asemenea cu unele învelișuri URL. Referiți-vă la Supported Protocols and Wrappers pentru lista învelișurilor care susțin familia de funcționalitate stat().

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;
}
?>

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 />';
}
?>

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.
