                              move_uploaded_file

   (PHP 4 >= 4.0.3)
   move_uploaded_file -- Moves an uploaded file to a new location

Description

   bool move_uploaded_file ( string filename, string destination)

   This function checks to ensure that the file designated by filename is
   a valid upload file (meaning that it was uploaded via PHP's HTTP POST
   upload mechanism). If the file is valid, it will be moved to the
   filename given by destination.

   If filename is not a valid upload file, then no action will occur, and
   move_uploaded_file() will return FALSE.

   If filename is a valid upload file, but cannot be moved for some
   reason, no action will occur, and move_uploaded_file() will return
   FALSE. Additionally, a warning will be issued.

   This sort of check is especially important if there is any chance that
   anything done with uploaded files could reveal their contents to the
   user, or even to other users on the same system.

     Note: When safe mode is enabled, PHP checks whether the files or
     directories you are about to operate on have the same UID (owner)
     as the script that is being executed.

     Note: move_uploaded_file() is not affected by the normal safe mode
     UID-restrictions. This is not unsafe because move_uploaded_file()
     only operates on files uploaded via PHP.

   Warning

   If the destination file already exists, it will be overwritten.

   See also is_uploaded_file(), and the section Handling file uploads for
   a simple usage example.
