mysql blob只接受图像吗？
我一直在网上寻找能够上传不同格式的更大的文件大小，但我只遇到图像教程。
我有下面的代码，在 if 语句并返回 echo 当我上传不同的文件类型大于10兆(该列为 LONGBLOB ).

<?php
ini_set('error_reporting', E_ALL);
ini_set('display_errors', 'On');  //On or Off

 session_start();
 require_once('connect.php');

    if(isset($_POST['submit'])){
         $file = rand(1000,100000)."-".$_FILES['file']['name'];
         $notes = mysqli_real_escape_string($connection,$_POST['notes']);
         $file_loc = $_FILES['file']['tmp_name'];
         $file_size = $_FILES['file']['size'];
         $file_type = $_FILES['file']['type'];

         $email = mysqli_real_escape_string($connection, $_SESSION['email']);
         $folder="uploads/";

          move_uploaded_file($file_loc,$folder.$file);

            $sql = "INSERT INTO `supportcontent` (`scontentdata`, `scontentnotes`, `suseremail`, `stype`,`ssize`)
            VALUES( '$file','$notes','$email','$file_type ','$file_size')";

            $current_id = mysqli_query($connection, $sql) 
            or die("<b>Error:</b> Problem on Image Insert<br/>" . mysqli_error($connection));
            if (isset($current_id)) {
                header("Location: landingpage.php?upload=success");
            }
        }
        else{       
            echo 'file is 0';
        }   
?>
