Problems with Symlink

[Mattys067]

Hi there, Im creating a online shopping cart and am coming across problems using the symlink function. Ive been told that it doesnt work on windows, however, my server is unix based. This is the code Im using and the corresponding error:

Code:

symlink("../imgage","imgage");

Error:

Warning: Symlink failed (File exists) in /data/httpd/docs/web/ShoppingCart/admin/make_symlink.php on line 2

Thanks in advance!
