filectime

(PHP 4, PHP 5)

filectime — Prende l'ora in cui l'inode del file è stato modificato

Descrizione

int filectime ( string $filename )

Restituisce l'ora in cui il file è stato cambiato l'ultima volta o FALSE in caso d'errore. L'ora viene restituita come un timestamp di Unix.

Nota: In molti filesystem Unix, si considera un file modificato, quando il suo inode viene cambiato; cioè quando i permessi, il proprietario, il gruppo o altri metadata dell'inode vengono aggiornati. Vedere anche filemtime() (che è ciò che ti serve se vuoi inserire la scritta "Ultima modifica: " nel piede delle tue pagine web) e fileatime().

Sappi anche che in alcuni testi su Unix si fa riferimento al ctime di un file come l'ora di creazione dello stesso. E' sbagliato. Nella maggioranza dei filesystem Unix non esiste un oa di creazione.

Nota: I risultati di questa funzione saranno memorizzati. Vedere clearstatcache() per maggiori dettagli.

Suggerimento

A partire da PHP 5.0.0, questa funzione può essere utilizzata con alcuni URL wrappers. Fare riferimento a List of Supported Protocols/Wrappers per la lista di quali wrappers supportano le funzioni della famiglia stat().

Example #1 Esempio di uso di fileatime()

<?php
 
// Visualizza ad esempio:  somefile.txt è stato modificato: December 29 2002 22:16:23.
 
$filename 'somefile.txt';
if (
file_exists($filename)) {
    echo 
"$filename è stato modificato: " date("F d Y H:i:s."filectime($filename));
}
 
?>

Vedere anche filemtime().

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.
