file handling problem

[ahobday]

Can anyone explain the weird error i am getting? I am running the script below which deletes any .txt files that are older than 7 days old.

$dh = opendir("./");
while (($filename = readdir($dh))!== false) {
if ((substr($filename, -4) == ".txt")&&(filemtime($filename) < (time()-604800))) {
unlink ("$filename");
}
}
closedir($dh);

The script runs fine when the current directory (./) is used. However I really want to run the script on a sub-directory called "files". However when i change opendir("./"); to opendir("./files"); i get the following errors:

<b>Warning</b>: filemtime() [<a href='http://www.php.net/function.filemtime'>function.filemtime</a>]: Stat failed for 991043164.txt (errno=2 - No such file or directory) in <b>/home/sites/www.testweb.xx/web/jt_site_22_11_02/cards/createcardsafe_rock.php</b> on line <b>72</b><br />
<br />
<b>Warning</b>: unlink(991043164.txt) [<a href='http://www.php.net/function.unlink'>function.unlink</a>]: No such file or directory in <b>/home/sites/www.testweb.xx/web/jt_site_22_11_02/cards/createcardsafe_rock.php</b> on line <b>73</b><br />

This suggests to me that the script is reading the directory and finding the files but when it comes to reading their creation date and deleting them it suddenly can't find them.

Can anyone tell me what i am missing?

try giving full path to the file, i mean full directory path not full url path to both of them.

Thanks for your reply but I have already tried the full path:
/home/sites/www.testweb.xx/web/site/cards/files/

what are the persmissions set to for the .txt files? That error could come up if they not set right. TXT permissions get reset each time you upload them, while not replacing an older version. Meaning it happens a lot, I always get caught by that.

Each textfile is created when a user submits a form:

$fp = fopen($card, "w");
fputs($fp, $name . "\n");
fputs($fp, $message . "\n");
fclose($fp);
chmod ("$card", 0777);

The text file then in theory remains in the directory for 7 days, after which the clean-up script is meant to remove it.
