unlink() returns TRUE but does not delete

[code green]

I have this piece of code to tidy up after a function that calls move_uploaded_file()

if(file_exists($destination.$filename))
{
    $exitmsg .= 
        "<br>File still in temporary location
        <br>$filename
        <br>Attempting deletion ";
    if(unlink($destination.$filename))
        $exitmsg .= '<br>Success deleting. Please try again ';
    else
        $exitmsg .= '<br>Failed deleting. Please inform IT';
    }

Basically I am attempting to delete a file from a
move_uploaded_file() 'destination' so that the file can upload. This piece of code returns TRUE but the file is still there

if(unlink($destination.$filename))

I am running Apache Windows with IE which I suspect is the issue.
Or am I completely mis-understanding unlink()?
By the way it is a CSV file.

Strange. You sure you've got permissions to delete it?

Furthermore, move_uploaded_file() will overwrite (I believe) the file if it already exists.

[prabirchoudhury]

you may set up directory permission, before calling unlink().

chmod("$destination", 0777);

move_upload_file() is called in a static class method.
This method checks if the file is already there before moving.
It then warns the user and handles the warning cleanly.

It is after this method that I want to delete the file so the user
can try again if they are happy.

I am not getting a permissions warning as expected but will try changing.
The strange thing is, if I refresh the page the file is then deleted.
And I am physically checking the directory.

The only things I can think of are a possible racing issue or
unlink() does not work well in Windows

I have had no problems with using unlink() with WAMP so it could be an issue with Apache I guess and its permissions. move_uploaded_file() does indeed overwrite any file of the same name. Perhaps its a problem with the class have you tried a simple test to remove the same file like:

echo unlink("Some Path Name");

And see if it returns true or false?

Its odd that it works on a refresh but not before.

Tried prabirchoudhury's suggestion. Wow that is hard to spell!
And did

chmod($destination, 0777); 

I was previously using

chmod($destination, 0666);

No idea what the difference is.
Also re-jigged the code so that the user can take a simpler course of action,
so it could be that I have inadvertently 'stepped over' the the problem.
Seems to be working now anyway, thanks for all the help.
