Replacing space with "_" when UL a file

[wooolF[RM]]

]Hello everybody

have a little problem here.
I wrote a little script to upload/download files to one specific folder on my host.

problem is : u can upload files with space in the filename, but then u can't download it, it will link to somethink like : http://www.bla.com/upload/bo instead of http://www.bla.com/upload/bo om.jpg

So I though that there may be a function replacing space with %20 or simple "_".

I tried to add

$file1=str_replace(" ","_",$file);

and then use code (after all checks for right extensions, file size limit etc)

@copy($file1, "$absolute_path/$file_name")

but it haven't helped...

I know it's really simple... but I can't hit it... :cross-eyed:

Can anyone help pls? Thanx!
