Renaming a directory through PHP

[cmdr_bond]

I got created a directory using PHP's mkdir command, but I want to rename the directory. Problem is that my ftp client wont let me since it says I dont have permission to do that (since it was php and not me who created the directory). I was wondering how I could rename the directory using php.
I created the a page with the following and chmod 777 but it didnt work:

 

<?
$old = "../images/1";
$new = "../images/2";
if (!rename($old, $new))
  	die ("rename error");

?>

And get the following error message:

Warning: rename(../images/1,../images/2): No such file or directory in [mypage] on line 4
rename error

Thanks

its just saying that ../images/1 doesnt exists. make sure the path is correct.
