$file_name = $_FILES["file"]["name"][$count];
$tmp_name = $_FILES["file"]['tmp_name'][$count];
$file_array = explode(".", $file_name);
$file_extension = end($file_array);
if(file_already_uploaded($file_name, $connect))
{
$file_name = $file_array[0] . '-'. rand() . '.' . $file_extension;
}
$location = 'files/' . $file_name;
if(move_uploaded_file($tmp_name, $location))
{
$stmt= $connect->prepare("INSERT INTO tbl_image (image_name) VALUES (:image_name)");
$stmt->bindParam(':image_name', $file_name);
$stmt->execute();
}
}
}
function file_already_uploaded($file_name, $connect)
{
$statement = $connect->prepare("SELECT image_name FROM tbl_image WHERE image_name = '".$file_name."'");
$statement->execute();
$number_of_rows = $statement->rowCount();
if($number_of_rows > 0)

Answer 1

store the image name as location with file name:
$location = 'files/' . $file_name;
if(move_uploaded_file($tmp_name, $location))
{
$stmt= $connect->prepare("INSERT INTO tbl_image (image_name) VALUES (:image_name)");
$stmt->bindParam(':image_name', $location.'/'.$file_name);
$stmt->execute();
}
