我下面的代码是所有关于上传文件，查看和下载它。我可以上传文件。我正在将文件名、文件大小、文件类型存储到数据库中。所以我的问题是，当我尝试上传.jmx文件和.zip文件时，它会被上传到所需的目录，但问题是它没有将文件详细信息存储到数据库中。在这方面谁能帮我一下吗。提前谢谢。
上传.php

<?php
include_once 'dbconfig.php';
if(isset($_POST['btn-upload']))
{    
 $file = rand(1000,100000)."-".$_FILES['file']['name'];
 $file_loc = $_FILES['file']['tmp_name'];
 $file_size = $_FILES['file']['size'];
 $file_type = $_FILES['file']['type'];
 $folder="C:\wamp64\www\uploads/";

 // new file size in KB
 $new_size = $file_size/1024;  
 // new file size in KB

 // make file name in lower case
 $new_file_name = strtolower($file);
 // make file name in lower case

 $final_file=str_replace(' ','-',$new_file_name);

 if(move_uploaded_file($file_loc,$folder.$final_file))
 {
  //$sql="INSERT INTO tbl_uploads(file,type,size) VALUES('$final_file','$file_type','$new_size')";
  $sql="INSERT INTO tbl_uploads(file,type,size) VALUES('$final_file','$file_type','$new_size')";
  mysqli_query($GLOBALS['db'],$sql);

  alert('error while uploading file');
        window.location.href='index.php?fail';
