Answer 1

PHP uploads the file into a temporary file and tells you where that is in the $_FILES['file']['tmp_name'] the $_FILES['file']['name'] holds the file name that the user called the file on their system, the one they select in the browser.
So if you want to grab the file before you have done a move_uploaded_file() on the file use $_FILES['file']['tmp']
$path = $_FILES['file']['tmp_name'];
$im = file_get_contents($path);
$imdata = base64_encode($im);
$horoscope = array("encode" => $imdata,
"path" =>$path,
"getcontents" =>$im
);
echo json_encode($horoscope);
I was not sure what you were passing back the $path for, so that may still need to be $_FILES['file']['name'].
$horoscope = array("encode" => $imdata,
"path" => $_FILES['file']['name'],
"getcontents" => $im
);
RE:Comment 1
I assume you want to store the base64encoded version of the file to the database so that will be $imdata
RE:Comment 2
To get the extension of the incoming file use pathinfo()
$path = $_FILES['file']['tmp_name'];
$file_parts = pathinfo($path);
$extn = $path_parts['extension'];
But beware, just because the extension says .png is not actual guarantee that it is a .png file
