For those using PHP on Windows and IIS, you SHOULD set the "upload_tmp_dir" value in php. 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 Image. Magick's convert utility.

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. Rob Szarka ¶9 years ago. Apparently the warning above might better be written "If the destination file already exists, it will be overwritten .. 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. 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: wheelbrentwientjes at NOSPAM dot comcast dot net ¶5 years ago.

I have for a couple of years been stymed to understand how to effectively load images (of more than 2. MB) 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 2. MB 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. The server may be adjusted with the . This example has an . Mphp_value upload_max_filesize 6.

Pic("your/file/structure/", 1. One more thing I want to mention about the post_max_size setting in php. 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 7. R nobody uploaddirchmod - R 7. 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 .
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 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? MB)$fsize = $_FILES["userfile"]["size"]; if($fsize == 0 || $fsize > 2. MB!!"); When the size is bigger than the MAX_FILE_SIZE field, the value of $fsize is equal to 0 (zero) ... When uploading a file with a very long filename, for example 2. The longest file I've succesfully uploaded has a 2. So, although you can create a 2.
Also, make sure that the setting for the post_max_size allows for a proper file size range. M ; Expands the size of POST data for file uploads. Harmor ¶8 years ago.
In addition to the file extension checking.

MIME type also (thus making the file extension check unnecessary)$temp = strpos($_FILES["pic"]["type"], "image"); if ($rep===FALSE){//the strpos function will return a boolean "false" ONLY if the needle string is not found within the haystackecho "is not an image"; }else{echo "is an image"; }ineedmynetwork. Microsoft returns image/pjpeg not image/jpg when using $_FILES['image.
Name']['type']; mancow at macfilez dot net ¶1. To nouncad at mayetlite dot com,That function will work fine for files with a 3- character file extension. However, it is worth noting that there are valid, registered file extensions that are longer than 3 characters. For example, a JPEG file can be denoted by *. Check out http: //www.
The best bet to me would be parsing the uploaded file's name ($_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!

PHP: is_uploaded_file - Manual. As of PHP 4. 2. 0, rather than automatically assuming a failed file uploaded is a file attack, you can use the error code associated with the file upload to check and see why the upload failed. This error code is stored in the userfile array (ex: $HTTP_POST_FILES['userfile']['error']). Here's an example of a switch: if (is_uploaded_file($userfile)) {//include code to copy tmp file to final location here..}else{switch($HTTP_POST_FILES['userfile']['error']){case 0: //no error; possible file attack! There was a problem with your upload."; break; case 1: //uploaded file exceeds the upload_max_filesize directive in php. The file you are trying to upload is too big."; break; case 2: //uploaded file exceeds the MAX_FILE_SIZE directive that was specified in the html formecho "The file you are trying to upload is too big."; break; case 3: //uploaded file was only partially uploadedecho "The file you are trying upload was only partially uploaded."; break; case 4: //no file was uploadedecho "You must select an image for upload."; break; default: //a default error, just in case! : )echo "There was a problem with your upload."; break; }Additionally, by testing the 'name' element of the file upload array, you can filter out unwanted file types (. Here's an example of a filter that can be added before testing to see if the file was uploaded: //rejects all . HTTP_POST_FILES['userfile']['name'])){exit("You cannot upload this type of file."); }//if file is not rejected by the filter, continue normallyif (is_uploaded_file($userfile)) {/*rest of code*/.
