move_uploaded_file

(PHP 4 >= 4.0.3, PHP 5, PHP 7)

move_uploaded_filePrzenieś uploadowany plik do innej lokalizacji

Opis

move_uploaded_file ( string $nazwa_pliku , string $przeznaczenie ) : bool

Funkcja ta sprawdza czy na pewno plik określony przez nazwa_pliku jest prawidło uploadowanym plikiem (to znaczy, że został uploadowany przez PHPowy mechanizm uploadowania HTTP POST). Jeśli plik jest prawidłowy, to zostanie przeniesiony do nazwy pliku wskazanej przez przeznaczenie.

Ten rodzaj testów jest szczególnie ważny jeśli istnieje szansa, że cokolwiek robimy z przysłanymi plikami może zdradzić ich treść użytkownikowi lub nawet innym użytkownikom tego samego systemu.

Parametry

nazwa_pliku

Nazwa wgrywanego pliku.

przeznaczenie

Miejsce docelowe przenoszonego pliku.

Zwracane wartości

Jeśli nazwa_pliku nie jest prawidło uploadowanym plikiem, to żadna akcja nie zostanie wykonana i move_uploaded_file() zwróci FALSE.

Jeśli nazwa_pliku jest prawidłowo uploadowanym plikiem, ale nie może zostać przeniesiony z jakiś powodów, żadna akcja nie zostanie wykonana i move_uploaded_file() zwróci FALSE. Dodatkowo, zostanie pokazane ostrzeżenie.

Notatki

Informacja:

Funkcja move_uploaded_file() jest świadoma tryb bezpieczny oraz open_basedir. Jednak, ograniczenia nałożone są tylko na ścieżkę przeznaczenie, ponieważ pozwala na przenoszenie uploadowanych plików w których nazwa_pliku może kolidować z takimi ograniczeniami. move_uploaded_file() zapewnia bezpieczeństwo tej operacji poprzez zezwolenie na przeniesienie tylko tych plików, które były uploadowane przez PHP.

Ostrzeżenie

Jeśli już istnieje plik docelowy, to zostanie on nadpisany.

Security tips you must know before use this function :

First : make sure that the file is not empty.

Second : make sure the file name in English characters, numbers and (_-.) symbols, For more protection.

You can use below function as in example

<?php

/**
* Check $_FILES[][name]
*
* @param (string) $filename - Uploaded file name.
* @author Yousef Ismaeil Cliprz
*/
function check_file_uploaded_name ($filename)
{
    (bool) ((
preg_match("`^[-0-9A-Z_\.]+$`i",$filename)) ? true : false);
}

?>

Third : make sure that the file name not bigger than 250 characters.

as in example :

<?php

/**
* Check $_FILES[][name] length.
*
* @param (string) $filename - Uploaded file name.
* @author Yousef Ismaeil Cliprz.
*/
function check_file_uploaded_length ($filename)
{
    return (bool) ((
mb_strlen($filename,"UTF-8") > 225) ? true : false);
}

?>

Fourth: Check File extensions and Mime Types that you want to allow in your project. You can use : pathinfo() http://php.net/pathinfo

or you can use regular expression for check File extensions as in example

#^(gif|jpg|jpeg|jpe|png)$#i

or use in_array checking as

<?php

$ext_type
= array('gif','jpg','jpe','jpeg','png');

?>

You have multi choices to checking extensions and Mime types.

Fifth: Check file size and make sure the limit of php.ini to upload files is what you want, You can start from http://www.php.net/manual/en/ini.core.php#ini.file-uploads

And last but not least : Check the file content if have a bad codes or something like this function http://php.net/manual/en/function.file-get-contents.php.

You can use .htaccess to stop working some scripts as in example php file in your upload path.

use :

AddHandler cgi-script .php .pl .jsp .asp .sh .cgi
Options -ExecCGI 

Do not forget this steps for your project protection.

The destination directory must exist; move_uploaded_file() will not automatically create it for you.

For those using PHP on Windows and IIS, you SHOULD set the "upload_tmp_dir" value in php.ini to some directory around where your websites directory is, create that directory, and then set the same permissions on it that you have set for your websites directory. Otherwise, when you upload a file and it goes into C:\WINDOWS\Temp, then you move it to your website directory, its permissions will NOT be set correctly. This will cause you problems if you then want to manipulate that file with something like ImageMagick's convert utility.

For those which will use inotify-tools to start an event when move_uploaded_file put the file in a specific directory, be aware that move_uploaded_file will trigger the create event, and not the move event of inotify-tools.

move_uploaded_file (on my setup) always makes files 0600 ("rw- --- ---") and owned by the user running the webserver (owner AND group).
Even though the directory has a sticky bit set to the group permissions!
I couldn't find any settings to change this via php.ini or even using "umask()".

I want my regular user on the server to be able to "tar cjf" the directory .. which would fail on files totally owned by the webserver-process-user;
the "copy(from, to)" function obeys the sticky-bit though!

nouncad at mayetlite dot com posted a function that uploaded a file, and would rename it if it already existed, to filename[n].ext

It only worked for files with extensions exactly three letters long, so I fixed that (and made a few other improvements while I was at it).

<?php
// Usage: uploadfile($_FILE['file']['name'],'temp/',$_FILE['file']['tmp_name'])
function uploadfile($origin, $dest, $tmp_name)
{
 
$origin = strtolower(basename($origin));
 
$fulldest = $dest.$origin;
 
$filename = $origin;
  for (
$i=1; file_exists($fulldest); $i++)
  {
   
$fileext = (strpos($origin,'.')===false?'':'.'.substr(strrchr($origin, "."), 1));
   
$filename = substr($origin, 0, strlen($origin)-strlen($fileext)).'['.$i.']'.$fileext;
   
$fulldest = $dest.$newfilename;
  }
 
  if (
move_uploaded_file($tmp_name, $fulldest))
    return
$filename;
  return
false;
}

Just a helpful comment.  If you have open_basedir set then you must set upload_tmp_dir to somewhere within the open_basedir.  Otherwise the file upload will be denied.  move_uploaded_file might be open_basedir aware, but the rest of the upload process isn't.

If you're dealing with files uploaded through some external FTP source and need to move them to a final destination, searching php.net for "mv" or "move" won't get you what you want. You want the rename() function.

http://www.php.net/manual/en/function.rename.php

(move_uploaded_file() won't work, since the POST vars won't be present.)

To nouncad at mayetlite dot com,

That function will work fine for files with a 3-character file extension.  However, it is worth noting that there are valid, registered file extensions that are longer than 3 characters.  For example, a JPEG file can be denoted by *.jpg (and others), but it can also have *.jpeg as a valid extension.  Check out http://www.filext.com/ for a good reference of file extensions.

The best bet to me would be parsing the uploaded file's name ($_FILES['uploadedfile']['name']) based on the presence of dots.  Another wrench in the gears:  a file can have dots in the filename.  That's easy enough to handle -- just explode() the file name and hope that the last element in the array it gives you is the file extension (you can always validate it if you're so inclined).  Then just piece it together in a string accordingly by stepping through the array (don't forget to add those dots back to where they were!), appending a guaranteed unique string of characters (or enumerate it like you were doing, keeping track via a loop), and finally tacking on the file extension.

You may have other mechanisms for verifying a file's extension, such as a preg_match on the whole name, using something like "/\\.(gif|jpg|jpeg|png|bmp)$/i" (more can, of course, be added if you so desire) for the most common types of images found on the web.

For blindly guaranteeing an uploaded file will be uniquely named, this seems like a fantastic way to go.  Enjoy!

It seems that move_uploaded_file use the GROUP permissions of the parent directory of the tmp file location, whereas a simple "copy" uses the group of the apache process. This could create a security nighmare if your tmp file location is owned by root:wheel

I have for a couple of years been stymed to understand how to effectively load images (of more than 2MB) and then create thumbnails.  My note below on general file uploading was an early hint of some of the system default limitations and I have recently discovered the final limit  I offer this as an example of the various missing pieces of information to successfully load images of more than 2MB and then create thumbnails.  This particular example assumes a picture of a user is being uploaded and because of browser caching needs a unique number at the end to make the browser load a new picture for review at the time of upload.  The overall calling program I am using is a Flex based application which calls this php file to upload user thumbnails.

The secret sauce is:

1.  adjust server memory size, file upload size, and post size
2.  convert image to standard formate (in this case jpg) and scale

The server may be adjusted with the .htaccess file or inline code.  This example has an .htaccess file with file upload size and post size and then inline code for dynamic system memory.

htaccess file:
php_value post_max_size 16M
php_value upload_max_filesize 6M

<?php
//  $img_base = base directory structure for thumbnail images
//  $w_dst = maximum width of thumbnail
//  $h_dst = maximum height of thumbnail
//  $n_img = new thumbnail name
//  $o_img = old thumbnail name
function convertPic($img_base, $w_dst, $h_dst, $n_img, $o_img)
  {
ini_set('memory_limit', '100M');   //  handle large images
  
unlink($img_base.$n_img);         //  remove old images if present
  
unlink($img_base.$o_img);
  
$new_img = $img_base.$n_img;
    
  
$file_src = $img_base."img.jpg"//  temporary safe image storage

   list(
$w_src, $h_src, $type) = getimagesize($file_src);     // create new dimensions, keeping aspect ratio
  
$ratio = $w_src/$h_src;
   if (
$w_dst/$h_dst > $ratio) {$w_dst = floor($h_dst*$ratio);} else {$h_dst = floor($w_dst/$ratio);}

   switch (
$type)
     {case
1:   //   gif -> jpg
       
$img_src = imagecreatefromgif($file_src);
        break;

unlink($file_src);  //  clean up image storage

Apparently the warning above might better be written "If the destination file already exists, it will be overwritten ... regardless of the destination file's permissions."

In other words, move_uploaded_file() executes as if it's root, not the user under which the web server is operating or the owner of the script that's executing.

I have looked at a lot of the file upload code listed below and other php documentation and have developed hopefully a robust single file upload routine.  I will later update with a multi file upload.  I have modestly tested the code.

<?php
//  5MB maximum file size
$MAXIMUM_FILESIZE = 5 * 1024 * 1024;
//  Valid file extensions (images, word, excel, powerpoint)
$rEFileTypes =
 
"/^\.(jpg|jpeg|gif|png|doc|docx|txt|rtf|pdf|xls|xlsx|
        ppt|pptx){1}$/i"
;
$dir_base = "/your/file/location/";

$isFile = is_uploaded_file($_FILES['Filedata']['tmp_name']);
if (
$isFile)    //  do we have a file?
  
{//  sanatize file name
    //     - remove extra spaces/convert to _,
    //     - remove non 0-9a-Z._- characters,
    //     - remove leading/trailing spaces
    //  check if under 5MB,
    //  check file extension for legal file types
   
$safe_filename = preg_replace(
                     array(
"/\s+/", "/[^-\.\w]+/"),
                     array(
"_", ""),
                    
trim($_FILES['Filedata']['name']));
    if (
$_FILES['Filedata']['size'] <= $MAXIMUM_FILESIZE &&
       
preg_match($rEFileTypes, strrchr($safe_filename, '.')))
      {
$isMove = move_uploaded_file (
                
$_FILES['Filedata']['tmp_name'],
                
$dir_base.$safe_filename);}
      }
   }
?>

I use $isFile and $isMove later in the code for error recording.

Make sure your system has the appropriate file loading limits. This caused a lot of headeaches trying to figure out why some files loaded and some did not.   In my case I have an .htaccess file in the root of the web site with:

php_value post_max_size 16M
php_value upload_max_filesize 6M

You may also need to extend the execution time depending upon the amount of data being transferred.

(sorry if spacing of code is a little off.  it was hard to make the note editor like the code style.)

I was getting error code 1 (http://www.php.net/manual/en/features.file-upload.errors.php), indicating that the file exceeded upload_max_filesize. To fix this, run <?php ini_set("upload_max_filesize", "100M"); ?> (then restart apache) changing the second argument to your limit.

If the user try to upload a too bigger file then the upload procedure will fail even if u have established an error message.
How to avoid this problem? there's my solution:

(max_file_size = 2,50 MB)

$fsize = $_FILES["userfile"]["size"];

if($fsize == 0 || $fsize > 2621000) exit("keep the filesize under 2,50MB!!");

When the size is bigger than the MAX_FILE_SIZE field, the value of $fsize is equal to 0 (zero) ......

A note for PHP on Windows IIS platform:
PHP does obviously not like directory traversing among partitions, so if you set upload_tmp_dir to be on different partition as php-cgi.exe or php.exe is, upload_tmp_dir will NOT be accessible for file uploads! You will get ERROR 6 on any attempt to upload file, and file size will be 0.
Resolution is to have upload_tmp_dir set to a path under PHP install folder.
...and make sure this folder (and also session_save_path folder) has at least read/write permissions granted to AppPool owner (usually NETWORK SERVICE) and IIS web user (by default IUSR_).

One more thing I want to mention about the post_max_size setting in php.ini that nobody else has mentioned.
If you try to upload a file larger than the post_max_size value (or multi files), the page will only refresh itself and no errors are thrown. It took me a while to figure the reason out.

If you have a directory in a *nix environment where you store all of your file uploads and your php script only seems to work when permissions for that directory are set to 777, here's how to fix it so that you can have the security benefits of 755 while still allowing your php scripts to work, including the move_uploaded_file().

through shell access, navigate to the directory that contains your uploads folder and run the following 2 commands:
chown -R nobody uploaddir
chmod -R 755 uploaddir

Replace 'uploaddir' with the name of your uploads directory. The first command changes the owner of the directory and files to 'nobody' which is what php operates under. The second changes the folder and files to only allow user access to writing. This is much more secure.

Hopefully this will help someone out there who had the same problem as me.

An extension only does not really tell you what type of file it really is. I can easily rename a .jpg file to a .zip file and make the server think it is a ZIP file with webmaster kobrasrealm's code.

A better way is to use the Linux utility "file" to determine the file type. Although I'm aware that some users might use Windows on their webservers, I thought it's worth  mentioning the utility here. Using the backtick operators and preg_matches on the output, you can easily determine the file type safely, and fix the extension when necessary.

If you find that large files do not upload in PHP even though you've changed the max_upload_size , this is because you need to change the max memory size varible too. The entire file is loaded into memory before it is saved to disk.

You can only move the uploaded file once.  You can use copy() if you need the file in more than one place.
<?php // RAY_temp_upload_example.php
error_reporting(E_ALL);
echo
"<pre>" . PHP_EOL;

// IF A FILE HAS BEEN UPLOADED
if (!empty($_FILES))
{
   
// SHOW THE UPLOADED FILES
   
print_r($_FILES);

   
// TRY TO MOVE THE FILE TWICE - SECOND MOVE RETURNS FALSE
   
if (!move_uploaded_file($_FILES["userfile"]["tmp_name"], $_FILES["userfile"]["name"])) echo "CANNOT MOVE {$_FILES["userfile"]["name"]}" . PHP_EOL;
    if (!
move_uploaded_file($_FILES["userfile"]["tmp_name"], $_FILES["userfile"]["name"])) echo "CANNOT MOVE {$_FILES["userfile"]["name"]}" . PHP_EOL;

   
// SHOW THE UPLOADED FILES AFTER THE MOVE - NO VISIBLE CHANGE
   
print_r($_FILES);
}

// END OF PHP, PUT UP THE HTML FORM TO GET THE FILE
?>
<!-- The data encoding type, enctype, MUST be specified as below -->
<form enctype="multipart/form-data" method="POST">
    <!-- MAX_FILE_SIZE must precede the file input field -->
    <input type="hidden" name="MAX_FILE_SIZE" value="300000" />
    <!-- Name of input element determines name in $_FILES array -->
    Send this file: <input name="userfile" type="file" />
    <input type="submit" value="Send File" />

When uploading a file with a very long filename, for example 255 characters, move_uploaded_file fails. The longest file I've succesfully uploaded has a 247 character filename. So, although you can create a 250 character filename locally the server may not be able to move it.

I have the same problem as the person two comments below me. When I use the move_uploaded_file function the permissions for the file are set to 0600. No matter what configurations you set.

I searched the internet and I found more people with the same problems, but no solutions. I set the umask of apache to 013 and still the files were set to 0600.

The copy function solves the problem. Another way to solve this problem is using the chmod function after uploading.

To use this function you must specify an array with min two parameters like that.
NAME is an optional parameter !
uploadFiles(array("FILES","DESTINATION","NAME"));

<?php

$file_one
= array($_FILES['file_one'],$destination,$name_one);
$file_two = array($_FILES['file_two'],$destination); //The name will be the same that $_FILES[]['name']

if(uploadFiles($file_one,$file_two)) {
    echo
"true";
} else {
    echo
"false";
}
?>

Nowhere does it say how to get the error/warning message when this fails.

The only way I know of doing it is something like this:

   if (move_uploaded_file($_FILES["file1"]["tmp_name"], $target_file)) {
      echo "<P>FILE UPLOADED TO: $target_file</P>";
   } else {
      echo "<P>MOVE UPLOADED FILE FAILED!</P>";
      print_r(error_get_last());
   }

Also, make sure that the setting for the post_max_size allows for a proper file size range.

post_max_size = 128M ; Expands the size of POST data for file uploads

Values upload_max_filesize and post_max_size (ie. php.ini values) cannot be modified in runtime with ini_set() function.
If you are using Apache web server, use .htaccess files with an IfModule replacing values corresponding to your file size and PHP version:

<IfModule mod_php4.c>
php_value upload_max_filesize 50M
php_value post_max_size 50M
</IfModule>

- means 50MB upload limit.

when you get this 2 Warnings - paths are a real sample - ::

-
move_uploaded_file(/uploads/images/sample.png) [function.move-uploaded-file]: failed to open stream: No such file or directory in /scripts/php/system/upload-file.php on line X
-

and

-
move_uploaded_file() [function.move-uploaded-file]: Unable to move '/tmp/somefilename' to '/uploads/images/sample.png' in /scripts/php/system/upload-file.php on line X
-

probably the path '/uploads/images/sample.png' is incomplete, in my case the complet path is "/home/x-user/public_html/uploads/images/sample.png"

you can use getcwd() to know the current working directory.

When you use move_uploaded_file function to upload a file with utf-8  filename to linux system, you probably check your result by browsing to see the file in the target directory so please make sure that your terminal emulator or your samba configuration is set the character encoding to utf-8 otherwise  your file will be shown as ?????? (unreadable character).

I could be wrong, but I usualy use

$uploadext = strtolower(strrchr($imagename,"."));

to find the file extension when uploading, as opposed to explode().

small typo:

$fulldest = $dest.$newfilename;

show be

$fulldest = $dest.$filename;

or you would have infinite loop.

Re: Florian S. in H. an der E. [.de]'s point about directory stick bits, I got hit by this a bunch since I use groups and dir sticky bits to secure my site, so I wrote this replacement, which others might find useful:

/**
* obey sticky bit with move_uploaded_file
*
*/
function wp_move_uploaded_file( $filename, $destination ) {
  define("STICKYGRPDIR",042010);
  $stat = stat(dirname($destination));
  if(move_uploaded_file($filename,$destination)) {
    if($stat['mode'] & STICKYGRPDIR) {
      return chgrp($destination,$stat['gid']);

I found a great resource concerning uploads with PHP:

http://www.radinks.com/upload/config.php

They explain and tell how to optimize PHP installation to handle large file uploads. Helped me a lot!

I once had a problem with this function. File was uploaded correctly, but I still had to chmod the file afterwards. It could not be used otherwise.

To retrieve the file extension, and various other information about the path, it is easiest to use the pathinfo function.

<?php
$path_parts
= pathinfo('/www/htdocs/index.html');

echo
$path_parts['dirname'], "\n";
echo
$path_parts['basename'], "\n";
echo
$path_parts['extension'], "\n";
?>

Would produce:

/www/htdocs
index.html
html
