Move upload file in php throwing error localhost

The file is not uploading can anyone explain how can I debug these errors.

Warning: move_uploaded_file(): The second argument to copy() function
cannot be a directory in
C:\xampp\htdocs\sanigo\my-account\Registerformcontroller.php on line
21

Second one:

Warning: move_uploaded_file(): Unable to move
'C:\xampp\tmp\phpEB06.tmp' to 'images/' in
C:\xampp\htdocs\sanigo\my-account\Registerformcontroller.php on line
21

my code:

$dir = 'images/'
$file = $_FILES['fileinputname']['tmp_name'];


move_uploaded_file($file , $dir );

Answer

The second argument of the move_uploaded_file needs to be a full path, including the file name.

For example:

$dir = 'images/'
$file = $_FILES['fileinputname'][tmp_name];

$new_file_name = 'foo.bar';

move_uploaded_file($file , $dir . $new_file_name);
