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 is available only in versions of PHP 3 after PHP 3.0.16, and in versions of PHP 4 after 4.0.2.

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.

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