Upload file filed

[Anon]

Hi, I tried to upload an image file as explained in php manual.
At my home It works.
Now I try to do the same at work (where I can connect to the main server using ssh): it doesn't work. The img_name is empty. The upload directory is "/tmp".
I can use fopen() in this dir but I can't see nothing inside.
Neither with copy(). The move_uploaded_file() tells me "Calls to undefined fn"
I tried different solutions, scripts, examples...so:
What I missed?

PS: I'm just a php beginner....please help me

function photo() {
GLOBAL $HTTP_POST_FILES;
for ($i=0;$i<sizeof($HTTP_POST_FILES["pics"]["name"]);$i++) {
$f_name = $HTTP_POST_FILES["pics"]["name"][$i];
if (strlen($f_name) > 3) {
copy($HTTP_POST_FILES["pics"]["tmp_name"][$i],"tmp/".$f_name);
}
}
} // end of function
