unlink not working

I'm a newbie to php. I am trying to delete a file from the server that I put
there (one file, not the whole directory). I am using unlink ($filename);

I did the path as a relative path as follows:
.../images/6/image_001.JPG

I did a scandir
$files = scandir("../images/6");

The print_r ($files); shows that the file is one of the files present.

On the possibility that it's a protection problem (though it shouldn't be,
as I put it there in the first place), I did a
chmod($filename, "777");

The file doesn't delete from the server. Any ideas?

Thanks!

One more thing that I forgot. If I do a var_dump(is_file($filename)); it
returns false, however using FTP, I see that the file is there, and another
page accesses it and brings it up, so it definitely is there.

777 is a really bad idea. It makes the file writable for all people with
access to the server.

Any error messages? Is error_reporting set to at least E_ALL and
display_errors enabled?

I did that immediately before doing the unlink, so that shouldn't be a
problem.

There were no error messages, but I don't have error_reporting set. I will.

BTW, the is_file being false was operator error. It returns true. It was
during a couple of trials that it was looking at something else I
misinterpreted it. So, the is_file says it is there, but the unlink doesn't
delete it.

On a development machine this should be done in the php.ini. The correct
values are

error_reporting = E_ALL|E_STRICT
display_errors = 1

Then check again if you get an error message on the unlink() call.

It is possible this is caused by using a relative path to the file you
want to delete. Try using the full path. Using some globals you can
quickly find the root path of your web server and start from there.

I tried $path = dirname(__FILE__) . '/../images/6/image_001.JPG

aand it still didn't delete.

I don't have access to the server's php.ini. the hosting company has that
controlled.

I put in error_reporting(E_ALL). I tried uploading another file (which I
intended to delete). I got the following error message:

Warning: move_uploaded_file() [function.move-uploaded-file]: open_basedir
restriction in effect. File(C:\WINDOWS\TEMP\php63.tmp) is not within the
allowed path(s):

However, using ftp, I can see that the file is there where it belongs and
the picture displays on the next page after the upload.

I then tried to delete the file and got this error message:

Warning: unlink(../images/6/image_007.JPG) [function.unlink]: Permission
denied

So, now I have three questions:
1 - Why did I get the error message on upload, yet it uploaded?
2 - Why didn't I get an error on chmod which appears immediately beofre the
unlink on which I got an error?
3 - Why did I get a permission denied problem for a file that I just put up
there/

Then try this at the top of your script:

ini_set('display_errors','1');
ini_set('display_startup_errors','1');
error_reporting (E_ALL);

And try referencing the file with something like
$_SERVER['DOCUMENT_ROOT'] . '/images/6/image_001.JPG';
