file - PHP Warning: move_uploaded_file() unable to move

I've been slowly learning PHP and have found an array of information on the subject and solutions posted by other developers. I am attempting to have an android application upload a file to PHP server via HTTP post. However something is not working on my server side wile attempting to write to file in PHP.

Here is the PHP code:

// Where the file is going to be placed
$target_path = "/var/www/media2net/uploads/uploads";

/* Add the original filename to our target path.
Result is "uploads/filename.extension" */
$target_path = $target_path . basename($_FILES['uploadedfile']['name']);

if (move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) {
    echo "The file ".  basename( $_FILES['uploadedfile']['name']) .
        " has been uploaded";
    chmod("uploads/" . basename($_FILES['uploadedfile']['name']), 755);
} else {
    echo "There was an error uploading the file, please try again!";
    echo "filename: " . basename( $_FILES['uploadedfile']['name']);
    echo " target_path: " .$target_path;
}

I already know from inspecting wire shark on client side that http post is sent out correctly, also I have ensured that the directory I'm writing the file to has the correct permissions, and php safe mode is set to off.

the output from apache2 error.log file reads

[Wed Dec 05 09:25:36 2012] [error] [client 74.14.162.250] PHP Warning:  
move_uploaded_file(): Unable to move '/tmp/phpVLOnn3' to  
'/var/www/media2net/uploads/downloaded_file.png' 
in /var/www/media2net/upload.php on line 9

Any help with this problem or further ways to trouble shoot this would be appreciated.

Change upload permissions for /var/www/media2net/uploads/ either by changing owner with "chown" or by "chmod"

Examples

$ sudo chown apache:apache /var/www/media2net/uploads/
$ sudo chmod 755 /var/www/media2net/uploads/

Also, if downloaded_file.png already exists in that directory and it's owned by another user, then you would need to change ownership on that file as well.

$ sudo chown apache:apache /var/www/media2net/uploads/downloaded_file.png

This way, it can be successfully overwritten by Apache.
