I used this code to find the temporary location of files(pictures) that users(me) upload to my site using a php upload script.
echo sys_get_temp_dir();
returns
C:\Users\a\AppData\Local\Temp
When I look in the temp folder I see some files with .tmp so I don't know if they are the ones downloaded. I'm trying to troubleshoot my PHP upload script. This is because I want to first verify the actual files are downloaded before I use the php move function.
Have a look at is_uploaded_file(). The $_FILES superglobal has information as well. And finally, the whole section about file uploads.
You are looking for is_uploaded_file function.

I have JS uploading to PHP which creates a /tmp/ file. Then JS lets the user to edit the meta data to send back to the API.
The JS then sends back to my php API:
"image":"#/tmp/test.jpg"
From that, I would like to invoke a $_FILES['image'] object to copy and move_uploaded_file with
Is this possible? Thanks!
Nope, that's impossible. The very purpose of move_uploaded_file() function is to check if the file were really uploaded, not faked by some API.
You can use copy() instead but make sure you took all the precautions.
For uploaded files, the manual states:
The file will be deleted from the temporary directory
at the end of the request if it has not been moved away or renamed.
So you can move_uploaded_file to your custom temporary directory and respond to your client-side application with a new file name. Then you will probably need to write a script which cleans your temporary directory at some time (using cron)
So a PHP program I built to download files from one server and upload them to another is now needed to rename the files.
For some reason I'm getting a 'invalid argument' warning on the rename() function which seems impossible because the file exists and there is 0 white space.
So now I was wondering if it was possible to rename a file as I download it from an ftp using ftp_get()?

Would suggest so. Give it a local file name.
Also make sure you are using rename() correctly

I am working on a csv import option on my php page. Is there any way to allow the user to upload a csv for processing and then destroy the file when it is complete? I have seen plenty of tutorials for uploading files, but none seem to mention something like this.
Sure! Take an upload script, and unlink() the file when you're done. Nothing to it.
Don't process the temporary file directly, though. Always move_uploaded_file() it to a directory you control. Then, delete it there.
When you upload a file to PHP it's stored in a temporary location, you can move it from there to a working directory, do your processing and then remove it.
$working_file = "/temporary/file";
move_uploaded_file($_FILES["file"]["tmp_name"], $working_file);
... // Do your processing on $working_file
unlink($working_file);
All you have to do is unlink() it when you've finished processing to delete it.

I'm uploading files via JS and storing the temp path in the session.
Than i use the following code to move the files.
if(move_uploaded_file($_SESSION['temp_img'][$key]['path'], $dest.$bigimg)){
$dest and $bigimg are defined earlier in the script with the id from the database.
Any Ideas or alternatives ?
MANCHUCK's answer was close but not quite there. You must call move_uploaded_file within the script where the file was uploaded. You cannot do what you're doing, that is, "storing temp path in the session" because that path is only valid for one request.
From the PHP manual:
The file will be deleted from the
temporary directory at the end of the
request if it has not been moved away
or renamed.
(Emphasis mine)
move_uploaded_file checks that a file has been uploaded to that page. You are actually uploading the file to a different PHP script then storing in a session. Instead of using move_upload_file use rename.
What is the output of $_SESSION['temp_img'][$key]['path'], also do you have permission to write to the web directory your placing the files. You may need to set it to 777 for some hosts to allow the webserver to write there.
I've seen ways to upload files directly to S3 and I've seen ways to upload a file already on the server. I need to modify the file's name before sending it on to S3, but I don't want to store it locally and then upload it, if I can help it. Is there a way to put it in a buffer or something? Thx.
The file will always end up in the temporary directory first while the upload completes, even before you're able to work with the uploaded file. You get all the file's chunks before, and then it get rebuilt in the /tmp directory by default. So no, there's no "pass-through". But I guess you could re-upload directly from the temporary directory afterwards instead of moving it to another working directory.
