file upload security issue

Hi everyone,

 

I try to learn file uploading in PHP.  I've successfully uploaded a file
onto my server.  I use move_uploaded_file("tmp_dir/tmp_filename",
"destination_dir/filename") to move the temp file.   The thing is that I
have to do a "chmod 777 destination_dir" in order to move the file.  Is
this bad for security?

 

Thanks  a lot in advance.
