delete file by date

[Anon]

I would like to delete files according to their date (how many days old, 7 days).

Can anyone help ?
Thanks !

Hi Peter,

See the following code. I hope it should help you. And mail me if it works - and let me know if you are in need to delete some specific type of file.In that case some two lines will be added to the program.

<?php
$handle=opendir('.');
/ if the program resides inside the directory from which files should be deleted. You have to change the file path if you need. /

while (($file = readdir($handle))!==false) {

$filetime=filemtime($file); 
/* when the file last modified */

$latesttime=time();
/* time just now */

$dtime=$latesttime-$filetime;

if($dtime>=604800)
/* 7 days x 24 hrs x 3600 seconds = 604800 seconds */

{
unlink($file);
/* delete the file */
 }

}
closedir($handle);
echo "success";
?>

cheers,

Pranab

Hello Paul,

I ran the script for 2 day delete instead of 7 but get some errors which I don't quite understand, what should I change.

here is what I get:

Warning: Unlink failed (Permission denied) in /web/inner1.com/old/deleteOLD.php on line 21
success

Here is line 21: unlink($file);

Here is the info of the files I want to delete, I chnaged the permissions of the 2nd file but it still could not be deleted:

-rw------- 1 web 1182 Mar 16 01:33 GAA4VF-6I.asc

-rwxr-xr-x 1 web 1231 Mar 16 00:49 GAA2RC-HGB.asc

What's the next step ?
Another thing I would like to do if possible is to open a particular directory and delete all subdirectories and their files !

Thanks

I just saw some code to change the file permissions and tried that without succcess, still get errors:

Warning: chmod failed: Not owner in /web/inner1.com/old/deleteOLD.php on line 21

Warning: Unlink failed (Permission denied) in /web/inner1.com/old/deleteOLD.php on line 24

Piece of code:

if($dtime>=172800) {
/ if($dtime>=604800) /
/ 7 days x 24 hrs x 3600 seconds = 604800 seconds /

/* chmod file to nobody */
chmod ($file, 0666); 

unlink ($file);
/* delete the file */
 }

}
closedir($handle);
echo "success";

Any suggestions ?
Thanks

You need to be the owner or at least have the rwx permission to the directory under which you want to delete the subdirectories and files. Try this thing by unix promt,telnet or ftp, change the chmod of the directory and the subdirectories to rwx (i.e, read write and execute). The code will be like this if you want to delete the subdirectories(which have no further subdirectories) and files:

<?php
$handle=opendir('.');

while (false!==($file = readdir($handle))) {
if ($file != "." && $file != "..") {

$occur=strstr($file,'.');  
$filetime=filemtime($file);
$latesttime=time();
$dtime=$latesttime-$filetime;
if($occur!="")
{
if($dtime>=604800)
{
unlink($file);
 }
 }
 else
      {

     $handle2=opendir($file);

while (false!==($file2 = readdir($handle2))) {
if ($file2 != "." && $file2 != "..") {

      $occur2=strstr($file2,'.');  
    if($occur2!="" && $dtime>=604800)
                {
            unlink($file.'/'.$file2);

            }
            }
            }
            closedir($handle2);
            rmdir($file);
 }

}
}
closedir($handle);
?>

Please use the instruction given in the previous message and the code written here. This one bug free and refined.

<?php
$handle=opendir('.');

while (false!==($file = readdir($handle))) {
if ($file != "." && $file != "..") {

$filetime=filemtime($file);
$latesttime=time();
$dtime=$latesttime-$filetime;

if(is_dir($file)!=true)
{ 
if($dtime>=604800)
{

unlink($file);

 }
}        else

           {

 	   $handle2=opendir($file);

while (false!==($file2 = readdir($handle2))) {
if ($file2 != "." && $file2 != "..") {

 	      if(is_dir($file2)!=true)
 	                {

 	           unlink($file.'/'.$file2);

 	            }
 	            }
 	            }
 	            closedir($handle2);
 	            rmdir($file);
 }

}
}
closedir($handle);
?>

Hi Paul,

I used the latest code and changed the directory & file permissions as :

drwxr-xr-x 2 web 512 Mar 27 12:30 old
-rwxr-xr-x 1 web 1231 Mar 16 00:49 GAA2RC-HGB.asc
-rwx------ 1 web 1182 Mar 16 01:33 GAA4VF-6I.asc

However I still get the error:
Warning: Unlink failed (Permission denied) in /web/inner1.com/old/delete3.php on line 18

Are these permissions correct ?
Any ideas !?

Thanks,
Peter

Hi Peter,

I do not know what kind of software you are using with php. But I am sending you a general solution for Unix system that may help you.

Say you have a directory named 'abc' inside the web route (or under some successive level) within which there are some directories and files those you want to delete.

In such circumstances put the program inside the directory 'abc' by ftp and change the chmod of the directory abc and all subdirectories under it to 777 or rwx.

If this does not work please let me know your system once.
