If I upload a text file via a form, is it possible to output its contents directly from the $_FILES variable rather than saving it onto the server first? I know this is a security risk, but it will only be run on a local machine.
Any advice appreciated.
Thanks.

In PHP, we can access the actual name of the file which we are uploading by keyword $_FILES[“file”][“name”]. The $_FILES is the by default keyword in PHP to access the details of files that we uploaded. The file refers to the name which is defined in the “index. html” form in the input of the file.
tmp_name is the temporary name of the uploaded file which is generated automatically by php, and stored on the temporary folder on the server. name is the original name of the file which is store on the local machine.
PHP $_FILES The global predefined variable $_FILES is an associative array containing items uploaded via HTTP POST method. Uploading a file requires HTTP POST method form with enctype attribute set to multipart/form-data.
$target_file specifies the path of the file to be uploaded.
Doing
file_get_contents($_FILES['uploadedfile']['tmp_name']); is valid however you should also check to make sure that the file was uploaded through a form and that no errors occurred during upload:
if ($_FILES['uploadedfile']['error'] == UPLOAD_ERR_OK //checks for errors && is_uploaded_file($_FILES['uploadedfile']['tmp_name'])) { //checks that file is uploaded echo file_get_contents($_FILES['uploadedfile']['tmp_name']); } A helpful link is http://us2.php.net/manual/en/features.file-upload.php
