Using uploaded file without saving to server disk

I have created a PHP script to upload a file, unfortunately I don't have permission to save files on the disk. I have to upload an excel file (using phpexcel), then I have to read all the rows in the f开发者_如何学Pythonile and save to disk, Is there any way for me to process this file without saving to disk, I tried to read $_FILES['file1']['tmp_name'] but it doesn't work.

could u please suggest a method to process this file

Thank you for the consideration

By "save to disk" you mean to send it back to the user for him to download it?

Usually, you shall have write access to (at least) the PHP temporary directory. Have you tried whether the form and script work in a local environment? Maybe there is something elso wrong with the upload?!

Finally: Why so you not have the persmission to save files? Are you allowed to create a subdirectory below you PHP file (via FTP) and give that one full permissions?

I tried to read $_FILES['file1']['tmp_name']

most probably you have just encountered an error.
that happens to beginner programmers very often

you have to repair that error instead of looking for odd workarounds.
Start from checking $_FILES['file1']['error']

what does

var_dump($_FILES['file1']['error']);

say?

Instead of sending your files with a form (multidata over HTTP POST), you can send your files with a little bit of Javascript with the HTTP PUT method to your server.

This scenario is described in the official documentation of PHP -> PUT method support.

Due some restrictions described in the documentation you have to do some workarounds to be able to work it properly.

You can read the direct input stream from your Webserver. The data will be piped from your Webserver to your PHP programm and will be only saved in memory. To do a PUT Ajax call with jQuery was answered here. You can use a jQuery upload plugin like Uploadify.
