How can PHP be used to store uploaded files temporarily on the server?

When users upload files to a server, it's important to store them temporarily before processing or moving them to a permanent location. PHP provides the `$_FILES` superglobal to access uploaded file information. To store uploaded files temporarily on the server, you can use the `move_uploaded_file()` function to move the file from the temporary directory to a desired location.

<?php
$uploadedFile = $_FILES['file']['tmp_name'];
$destination = 'path/to/temporary/directory/' . $_FILES['file']['name'];

if(move_uploaded_file($uploadedFile, $destination)){
    echo 'File stored temporarily on the server.';
} else {
    echo 'Error storing file.';
}
?>
