version upgrade causing upload error

[rikmoncur]

A server's just upgraded from PHP version 4.1.2 to PHP version 4.4.2.

My file uploading script is now throwing the following error:
(I've replaced the actual server path with MY SERVER PATH)

Warning: move_uploaded_file(): open_basedir restriction in effect.
File(/MY SERVER PATH /testpdf2.pdf) is not within the allowed path(s): (/MY SERVER PATH/httpdocs:/tmp) in /MY SERVER PATH/uploader.php on line 95

The bit of my script is:

/*  In PHP versions earlier than 4.1.0, $HTTP_POST_FILES should be used instead of $_FILES. */

$uploaddir = '/*MY SERVER PATH*/pdf/';
$uploadfile = $uploaddir . basename($_FILES['userfile']['name']);
/* move_uploaded_file(string filename, string destination) */
if (move_uploaded_file($_FILES['userfile']['tmp_name'], $uploadfile)) 
{
   echo "File is valid, and was successfully uploaded.";
} 
else {
   echo "Failed";
}

Line 95 is the beginning of the 'if' statement - ie:
if (move_uploaded_file($_FILES['userfile']['tmp_name'], $uploadfile))

I originally got this script from zend:
http://www.zend.com/manual/features.file-upload.php

Anyone got a clue what's busted?

Fixed it.
Had a bit of a fiddle and seems the server path needed changing:

$uploaddir = '/*MY SERVER PATH*/pdf/';
$uploadfile = '/*MY SERVER PATH*/pdf/' . ($_FILES['userfile']['name']);
