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.

Handling file uploads
