Change file name to uniqid in PHP

Question

I am looking to modify my code below to accept a randomly generated unique id to replace the name using php uniqid function. I have tried a couple ways with no success.

 move_uploaded_file($_FILES["file"]["tmp_name"],
 "upload/" . $_FILES["file"]["name"]);
 $ipath = "upload/";
 $ipath .= $_FILES["file"]["name"];

Does anyone know how I can accomplish this?

Edit: I am asking where to put the uniqid function so that the file is stored with the uniqid.extension in the folder on my server.

Answer 1

move_uploaded_file($_FILES["file"]["tmp_name"],
    "upload/" . uniqid());

or, if you want to keep the file extension:

$fileInfo = pathinfo($_FILES["file"]["name"]);

move_uploaded_file($_FILES["file"]["tmp_name"],
    "upload/" . uniqid() . '.' . $fileInfo['extension']);

\\edit: to use the $ipath variable...

$fileInfo = pathinfo($_FILES["file"]["name"]);
$ipath = "upload/" . uniqid() . '.' . $fileInfo['extension'];
move_uploaded_file($_FILES["file"]["tmp_name"], $ipath);
