CHMOD error

[dcgamers]

I am tring to chmod a file using the following code:
[code]
<?
$imm = "$_GET[url]";
chmod("$imm", 755);
?>
[/code]
and I get the following:
Warning: chmod() [function.chmod]: Operation not permitted in /home/****/public_html/****.php on line 3
Please help!

Im not sure but are you logged in as an adminastrator?

[dcgamers]

how would I know?

Well first, what are you setting $_GET[url] do note that this would be ****.php?url=[b]whatever.end[/b] Not the actual url.

A cleaner way to set $imm would be like

$imm = $_GET['url'];

then use

chmod($imm, 755);

It wont change the function but clean code is good code.

ok but I still have a problem that no one seems to help me with

[icicleman]

What I was trying to say is if you are not logged in as an adminastrator then you cant change permmissions

If the file your trying to chmod on isn't in the same folder you may get this error. Also... are you running on windows?

Also maybe try...

[code]<?php
$imm = $_GET['url'];

if (chmod($imm, 755))
  echo "I don't care what the error message says, I did the job.";
else
  echo "About what you told me to do... yeah... slight problem there.";

?>[/code]

very funny. My server is a Linux. I tested the function on a file in the same folder and it got that error and not being in the same directory has nothing to do with this error.

Try

[code=php:0]<?
$imm = "$_GET[url]";
$fstats = fstat($imm);
if (!$fstats) {
  die("Couldn't fstat() $imm");
}
$file_uid = $fstats['uid'];
$my_uid = getmyuid();
print "File is owned by $file_uid, my uid is $my_uid\n";
?>[/code]


If the fstat() fails, then you may be looking in the wrong directory, or you may not have permission to read the directory the file is in.  If the uids don't match, then that is why you cannot change permissions on that file.

uggg.....
right directory:
Warning: fstat(): supplied argument is not a valid stream resource in /home/****/public_html/****.php on line 3
