Cheers, tedd -- --- http://sperling.com http://ancientstones.com http://earthstones.com I think it's more likely that a security flaw might be found which allows code other than yours to run. Buffer overflows were notorious for this, as they had the side-effect of running whatever ran outside of their buffer range, so you could in effect get a system with an overflow hole to run whatever code you wanted. Usually a problem like this would be limited to a specific function, but if someone was able to guess correctly that you were using this function then they could potentially form code that exploited it.

[PHP] unlink file rights problem
Hi there, I am trying to unlink a file which is inside a folder that is not writable to phps user www. Of course this failes, but I need to find a solution for it. Backgroud is following: I have pure-ftpd installed where user directories get created by pure-ftpd. Unfortunatelly there seems to be a bug and pure-ftpd does only create the homedirectory folder in 750 mod. My PHP-Script scans this directories every x minutes and processes those files. Upon completinon those files should get deleted, but as the dir is not writable by the user www this failes. The dir looks like this: drwxr-x--- 2 ftpuser ftpgroup 4096 Jan 28 10:18 merlin/ files inside look like this: -rwxrwx--- 1 ftpuser ftpgroup 16868 Jan 28 10:20 test.xml* User www which executes php via cron is inside the group ftpgroup. Any ideas? I am kind of lost with this one. Thank you for any help! Best regards, Merlin -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] PHP unlink Permission Error
Hi,
I have a snippet of code as follows:
?php
ini_set('display_errors', 1); error_reporting(E_ALL);
$curDir = getcwd();
echo $curDir;
chmod($curDir,0777);
unlink(testFile.txt);
echo unlink(testFile.txt);
chmod ($curDir,0755);
?
The problem is that I do not seem to have the correct permissions, even though
I seem to have changed the permissions of the folder to 777 already upon the
file deletion time. This is the output I got:
C:\Inetpub\wwwroot\projectWarning: unlink(testFile.txt) [function.unlink]:
Permission denied in C:\Inetpub\wwwroot\project\file_write.php on line
9Warning: unlink(testFile.txt) [function.unlink]: Permission denied in
C:\Inetpub\wwwrootproject\file_write.php on line 10
Could anyone give me some tips on how to resolve this error? Thanks in advance.

You're using chmod to modify the permissions of the directory, but do
you actually have permissions to modify the permissions? If not, the
chmod will fail without giving an error, and then your unlink will fail

Re: [PHP] PHP unlink Permission Error
Not only do you need to check the return value of chmod to see if it worked, but also, I *think*: The file withing the directory can have entirely different permissions, and making the directory world writable won't help that, I don't think... I could be wrong, and a 000 file in a 777 dir might be unlink-able.

[PHP] PHP unlink Errors
Hi,
I have a snippet below that I would like to delete a file. However, I keep
getting kicked out because of permission errors, when my folder permission is
0777.
?php
ini_set('display_errors', 1); error_reporting(E_ALL);
$curDir = getcwd();
chmod($curDir,0777) or die (Failed to change permission);
echo substr(sprintf('%o', fileperms($curDir)), -4);
unlink(C:/Inetpub\wwwroot/project/testFile.txt);
echo unlink(C:/Inetpub/wwwroot/pproject/testFile.txt);
?
Is it possible that someone on the list could point out what my possible errors
are to allow this code to be functioning?
Here is the output:
0777Warning: unlink(C:/Inetpub\wwwroot/project/testFile.txt) [function.unlink]:
Permission denied in C:\Inetpub\wwwroot\project\file_write.php on line
9Warning: unlink(C:/Inetpub/wwwroot/project/testFile.txt) [function.unlink]:
Permission denied in C:\Inetpub\wwwroot\project\file_write.php on line 10
Thanks in advance.

Do you have php_safe_mode enabled? If's that's the case, try turning it
off and then run your script again.

Just because you have perms to change the dir and have set the dir to
777 doesn't mean you have perms to delete the file? Who is the owner of
the file and what are the perms?

RE: [PHP] PHP unlink Errors
Hi,
Apparently my safe mode is off. I tried fiddling with my code by changing the
permission of my intended to delete file as in the following:
?php
ini_set('display_errors', 1); error_reporting(E_ALL);
$curDir = getcwd();
chmod($curDir,0777);
echo substr(sprintf('%o', fileperms($curDir)), -4);
$fileToRemove = C:/Inetpub/wwwroot/project/testFile.txt;chmod ($fileToRemove,
0777) or die (permission canonot be set);
echo substr(sprintf('%o', fileperms($fileToRemove)), -4);
if (@unlink($fileToRemove) == true) {
unlink($fileToRemove);
} else {echo You don't have the permission;}
?
This is the output I get
07770666You don't have the permission
I don't get a failure statement in the line: chmod ($fileToRemove, 0777) or die
(permission canonot be set);, how come the permission of this file is still
0666?
Thanks in advance.

Re: [PHP] PHP unlink Permission Error
Alice, I see that you are using windows. For windows only the write permission for the folder and file isn't enough. You need to change the owner ship of the file as well so that u have privilege to delete. Do this , this might work: //Change the owner ship of the file to a non existent user in the system chown($directory./.$file,666); unlink($directory./.$file); Thanks, V
[PHP] unlink oddity
Ok, here is my problem. Using the code below, I am saving a posted form to
a database including the files it contains.
There is one line commented out.. The unlink command. Without the command,
the script works fine and new files
Overwrite the old files when uploaded. If, however, I uncomment the unlink
line, the new files are still saved and the
if (file_exists($path)) { line evals to true, but the file disappears
after program
Execution. The net result of having the unlink command in seems to be that
it executes
after program termination leaving a record of the successful upload in the
database, but
no file found on the server where the upload occurred. Does anyone have any
idea of
why this would be occurring? The php docs for unlink do not talk about
delayed execution
and other scripts I researched seems to use unlink before the move command
with success.
Any help would be greatly appreciated.

Why not just unlink($path) ? It's the same thing but you take 2
variables out of the problem.
While you're trying to debug this remove the '@' signs. An error message
will be particularly useful.
Check your logs if you can, otherwise turn up error reporting and
display errors until you work out what's going on.
error_reporting(E_ALL);

Read docs!
You too! The OP wanted a way to check the age of all files. The
fileatime function will return when the file was last accessed.
Accessing a file is not usually deemed to affect its age, modifying it
is. The filemtime function is what the OP wants.
Unless he wants filectime, for when the file was created, even if it's
been modified in the past week...
older could mean that, in some contexts...
I think finding all the .txt.asc files would best be handled by
http://php.net/glob unless your PHP version is too old and you need to
http://php.net/opendir and http://php.net/readdir to look at each file

You too! The OP wanted a way to check the age of all files. The
fileatime function will return when the file was last accessed.
Accessing a file is not usually deemed to affect its age, modifying it
is. The filemtime function is what the OP wants.
Unless he wants filectime, for when the file was created, even if it's
been modified in the past week...
older could mean that, in some contexts...
I think finding all the .txt.asc files would best be handled by
http://php.net/glob unless your PHP version is too old and you need to
http://php.net/opendir and http://php.net/readdir to look at each file
in turn...

something like:

do whatever with old files

off the top of my head.
There are other ways to do it.

[PHP] unlink, symlink and caching
I have a directory with the files:
/config/A
/config/B
and
/config/C is a symlink to /config/A.
Via php I unlink /config/C:
$FILE = '/config/C';
while(file_exists($FILE)){
unlink($FILE);
clearstatcache();
}
When run, the first time through the loop $FILE is removed from disk
as it should.
The loop then continues forever with file_exists() returning true, but
unlink() returns false with the error message Warning:
unlink(/config1/C) [function.unlink]: No such file or directory in
/www/script.php on line 10
If I do this:
$FILE = '/config/C';
unlink($FILE);
cleanstatcache();
symlink('/config/B', '/config/C');
I get the error message:
Warning: symlink() [function.symlink]: File exists in /www/script.php
on line 11
However the link had been deleted.
The symlink /config/C is read via file_get_contents() before the
unlink and relink is performed.
I have also done the following:
$FILE = '/config/C';
unlink($FILE);
`ln -s /config/B /config/C`
Which works as expected, the old link is replaced with the new link,
however any attempt to open and read from the new link returns the
contents of the old file.
How would I be able to get the expected behavior from PHP. I expect
that the problem has something to do with the symlinks being used.
Any assistance is appreciated.

Thank you for checking on this.
I am using debain stable with a 2.6.14.3 kernel. The filesystem in
question is ext2 on a 48 MB ramdisk.
I also did the following on another machine using ext2 on a harddisk
with command line php.
?php
/*
-rw-r--r-- 1 user user 0 Dec 21 12:41 A
-rw-r--r-- 1 user user 0 Dec 21 12:41 B
lrwxr-xr-x 1 user user 1 Dec 21 12:43 C - A
-rw-r--r-- 1 user user 91 Dec 21 12:41 test.php
*/
$FILE = 'C';
while(file_exists($FILE)){
echo $FILE exists\n;
echo `ls -l C`;
if(!unlink($FILE)){
echo Unable to delete $FILE\n;
echo `ls -l C`;
}else{
echo Deleted $FILE\n;
}
echo \n;
}
/*
Output:
php5 ./test.php
C exists
lrwxr-xr-x 1 user user 1 Dec 21 12:59 C - A
Deleted C
C exists
ls: C: No such file or directory
Warning: unlink(C): No such file or directory in
/home/user/x/test.php on line 14
Unable to delete C
ls: C: No such file or directory
C exists
ls: C: No such file or directory
Warning: unlink(C): No such file or directory in
/home/user/x/test.php on line 14
Unable to delete C
ls: C: No such file or directory
*/
?
This shows that apache is not responsible for the problem.
Note also that if I delete A and C within the loop the code works as
expected and the loop only executes once. So file_exists() is seeing
A when I tell it to delete C and unlink is seeing C as it
should.
Any ideas where to start to look for the cause of the problem?

RE: [PHP] unlink images
What you may want to try doing is when the script is ran, it goes through a clean-up function and deletes everything that it doesn't need for the current execution. Though, realize that if two people hit a page within a few seconds, you may end up deleting some images that the first user is trying to get rid of. You'll have to judge the traffic for yourself and figure out if this is a viable option. Other solutions that I can think of is after the page is ran you update a text file with the names of the images that are to get deleted and just run a cronjob to read this file and delete the files in there. Similarly, you could add the names to a db table with a timestamp and delete all files that are older than a particular time. Many options, but you have to figure out what works best for you. -M -Original Message- From: Julian [mailto:[EMAIL PROTECTED] Sent: Friday, November 26, 2004 2:14 PM To: [EMAIL PROTECTED] Subject: [PHP] unlink images Hello, I would like to delete a set of images right after they are displayed on the page using unlink.

Re: [PHP] unlink() rmdir() ... Problems.
The reason this works is because you are doing a recursive remove of
the directory. The PHP rmdir() does not remove a directory with
contents in it. If you modify your script so that it walks the users
directory and removes each file and subdirectory then it would
probally have worked correctly.
I would have mentioned this earlier but I have been away from email
for the past day or so.

Btw, be extra careful what $user_dir is, if somehow it is / you'll
delete any file that nobody has permission to; which isn't a good

[PHP] unlink() rmdir() ... Problems.
Ave,
I do not really know what the problem is because I don't get an error, and
in fact my scripts execute fine... Except that, niether is the directory
deleted, nor is the file deleted. Only corresponding database entries are
deleted which I specify in my SQL code.
There are 2 different functions in 2 separate places in my File Manager.
1 function deletes the User including his Folder
The other deletes a particular file.
The code I'm using to delete the User his Folder is:
?php
if($delete_user) {
$db = mysql_connect(localhost,usr,pwd);
mysql_select_db(mydb,$db);
$sql = DELETE FROM user where login = '$user';
$result = mysql_query($sql) or die(There is a problem.);
$sql2 = DELETE FROM file where login = '$user';
$result2 = mysql_query($sql2) or die(There is a problem.);
rmdir (imsafm/$user);
echo brbismallUser $user deleted./small/i/bbr;
}
?
The name of Folder of a user is the same as his Login.
Anyhow... The above code doesn¹t generate any error, and in fact does delete
the database entries from the table... But it doesn¹t remove the user¹s
directory. Why is that?
Similarly, this is the code for deleting the file:
?php
$db = mysql_connect(localhost,usr,pwd);
mysql_select_db(mydb,$db);
$sql = DELETE FROM file where ID = '$ID';
$result = mysql_query($sql) or DIE(Cannot Do!);
unlink($P/$F);
echo centerFile Deleted/center;
?
Again, no error... The entries in the table get deleted.. But file remains
in the directory.
Any suggestions?

Re: [PHP] unlink() rmdir() ... Problems.
PHP probably does not have permission to change those files. chmod 777
and it should work.
However now those files are writable by anyone. If you're on a shared
server there could be problems later.

rmdir (imsafm/$user);
echo brbismallUser $user deleted./small/i/bbr;
}
?
The name of Folder of a user is the same as his Login.
Anyhow... The above code doesn¹t generate any error, and in fact does delete
the database entries from the table... But it doesn¹t remove the user¹s
directory. Why is that?
Similarly, this is the code for deleting the file:
?php
$db = mysql_connect(localhost,usr,pwd);
mysql_select_db(mydb,$db);
$sql = DELETE FROM file where ID = '$ID';
$result = mysql_query($sql) or DIE(Cannot Do!);
unlink($P/$F);
echo centerFile Deleted/center;
?
Again, no error... The entries in the table get deleted.. But file remains
in the directory.
Any suggestions?

[PHP] php unlink a file - is it possible?
Hi, How can have a php script unlink/delete a file uploaded via FTP? Usually a ftp-uploaded file belongs to the ftp user, and a php script is running by apache/nobody. Seems like there shouldn't be any way to do this...OK, my situation is that I want a php script to this: it can move bulk uploaded (ftp) file to certain directories and then remove the original files, something just like a move. If anyone knows on how to move or delete a file, please give me a hand. Thanks in advance! Alex -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] php unlink a file - is it possible?
Unless you change the permissions of the file, the run the FTP as nobody, run apache as the ftp user, run apache as root (can't believe I even said that... blasphemy!), etc., it shouldn't be possible. If you find a way to do it w/out any of the above, I'd suggest you email the Apache Software Foundation and/or the FTP software people, as well as [EMAIL PROTECTED], [EMAIL PROTECTED], etc. That being said, would it be feasible to set up a cron job to do this w/ the PHP CLI running as an appropriatly privledged user?

1) You do not define $dir_to_upload, nor $Photo (at least in your example)
- this would lead to
$result=unlink('/');
hence error 1.
2) You don't define the variable $id (at least in your example), so the SQL
statement would read
update product set .
Photo='nothing', miniPhoto='nothing', picture='0' .
where ID=
hence error 2 (after ID=).
If these values are available on a global level, you must declare them
global within your function.

There are also errors in how you format the filename passed to unlink(),
and in formatting the SQL statement - see below.
Do yourself a favour and make the following modification to your script and
look at the output:
if (isset($delimage))
{
$file = $dir_to_upload/{$row-Photo};
$sql = update product set Photo='nothing', miniPhoto='nothing', .
picture='0' where ID='$id';
echo unlink($file);br /query($sql);br /;
$result=unlink($file);
$result=mysql_query($sql) or die

At 16:42 26-2-03, you wrote:

what do you get when you echo
echo htmlspecialchars('$dir_to_upload/$row-Photo');
and do you use the full file path? Images accept relative links but in my
experience PHP's file handling functions want the full path.

Fw: [PHP] unlink ($files);
Hi,
You can use the backtick operator to delete whatever you have
permissions to delete:
$directory = path/*.*;
`rm -rf $directory`;
They aren't quotes, they are backticks (to the left of the 1 key on most
keyboards). It is very useful for any command line stuff you have
permissions to do.

Re: [PHP] unlink ($files);
Can't do wildcards like * because thats something that as I found out a few days ago, is expanded by the shell into a full command, so because your not running a shell, it can't be expanded and the raw unlink call to *.* fails because the unlink function doesn't understand wildcards. If you really want to do a recursive deletion (i.e., remove both a directory and everything under it) you could use: exec(/bin/rm -rf path/$name-of-dir-to-be-erased); Just be very sure about what your doing (multiple checks on the variable's value to make sure your not erasing anything you don't want to) cause this command, when executed with the proper permissions, will kill any directory and everything under it.

Re: [PHP] unlink ($files);
That will usually work on Unix but will not work on Windows. Rather than executing an external program you can use PHP itself to do a recursive delete. There are examples at http://www.php.net/manual/en/function.rmdir.php if you read the user notes you will see several posts about doing this.
