move_uploaded_file — Moves an uploaded file to a new location
This function checks to ensure that the file designated by from
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 to
.
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.
from
The filename of the uploaded file.
to
The destination of the moved file.
Returns true
on success.
If from
is not a valid upload file, then no action will occur, and move_uploaded_file() will return false
.
If from
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.
Example #1 Uploading multiple files
<?php
$uploads_dir = '/uploads';
foreach ($_FILES["pictures"]["error"] as $key => $error) {
if ($error == UPLOAD_ERR_OK) {
$tmp_name = $_FILES["pictures"]["tmp_name"][$key];
// basename() may prevent filesystem traversal attacks;
Note:
move_uploaded_file() is open_basedir aware. However, restrictions are placed only on the
to
path as to allow the moving of uploaded files in whichfrom
may conflict with such restrictions. move_uploaded_file() ensures the safety of this operation by allowing only those files uploaded through PHP to be moved.
If the destination file already exists, it will be overwritten.
