我正在尝试使用 PHP 和 MySQL 将视频上传到数据库。我可以将小视频文件上传到网站和数据库，但是当我使用中到大文件大小时，它会出现错误。我已经尝试更改 php.ini 文件，但仍然有同样的问题。我的上传表单代码有问题吗？我可以通过 phpmyadmin 手动添加大文件，但不能通过表单。

<?php
    require('inc/connection.php');
    require('inc/function.php');

    //ToDo header title
     $header = "Upload";
    require('inc/header.php');


    if(isset($_GET['status'])){
    $header = "successed";
    if($_GET['status']=='uploaded'){
        echo '<br><br><br><br>';
        echo '<h1><center> :) </h1>';
        echo '<p><center>Your Video upload is successful.</p>';
        die();
        }
     }

    //header title
    $header = "Upload";

    //if not Loggedin redirect to the main page
    if(!loggedin() || checkAdmin()){
    header('Location: index.php');
    }
    if($_SERVER["REQUEST_METHOD"] == "POST"){
    
    //Filtering input
    $title = trim(filter_input(INPUT_POST,"title",FILTER_SANITIZE_STRING));
    $description = trim(filter_input(INPUT_POST,"description",FILTER_SANITIZE_SPECIAL_CHARS));
    
    //Files to be uploaded
    $vid_tmp_name = $_FILES['video']['tmp_name'];
    $thumbn_tmp_name = $_FILES['thumbnail']['tmp_name'];
    
    //Check if empty (required fields)
    if(empty($title) || empty($vid_tmp_name)|| empty($thumbn_tmp_name) ){
            $error_message[] = "Please fill in the required fields: Title, 
    Video and Thumbnail.";
    }
    if(empty($description)){
        $description = "(NULL)";
    }
    if(strlen($title)>70){
        $error_message[] = " Title must be less than 70 character.";
    }
        
    if(!isset($error_message)){
        loader("Please Wait .. ");
        //date of the video
        $t=time();
        $date=date("M d, Y",$t);
        
        //name of the video & thumbnail
        $d = date_create();
        $name = date_timestamp_get($d);
        
        if (!is_dir('./media/video/')) {
            mkdir('./media/video/', 0755, true);         
        }
        if (!is_dir('./media/thumbnail/')) {
            mkdir('./media/thumbnail/', 0755, true);         
        }
        
        try{
            //Full direction of both video & thumbnail
            $vid_uploads_dir = './media/video/'.$name.'.mp4';
            $thumbn_uploads_dir = './media/thumbnail/'.$name.'.jpg';
            
            //Start uploading
            move_uploaded_file($vid_tmp_name, $vid_uploads_dir);
            move_uploaded_file($thumbn_tmp_name, $thumbn_uploads_dir);
            //Add video metadata to the DB
            addVideoRequest($title, $description, $_SESSION['id'], $name, 
    $name, $date);
        }catch(Exception $e){
            $error_message[] = "Error : ".$e->getMessage();
        }
       }
      if(isset($error_message)){
    echo '<div class="wrapper"><div 
     class="error">'.$error_message[0].'</div></div>';
      }else if(is_file($vid_uploads_dir) && is_file($thumbn_uploads_dir) ){
        //if the uploaded do exist then
        //Redirect to this page
        header('refresh:1;url=upload.php?status=uploaded');
        //header('Location: upload.php?status=uploaded');
    }else{
        $error_message[] = "Error occurred, Please try again !!";
       }
    }
    ?>

        <div class="wrapper content">
    <form action="upload.php" method="POST" enctype="multipart/form-data" class="form">
        <table>
            <tr>
                <th>Title *</th>
                <td><input type="text" name="title"  maxlength="70"></td>
            </tr>
            <tr>
                <th>Video *</th>
                <td><input type="file" name="video" accept="video/*"></td>
            </tr>
            <tr>
                <th>Thumbnail *</th>
                <td><input type="file" name="thumbnail" accept="image/*"></td>
            </tr>
            <tr>
                <th>Description</th>
                <td><textarea rows="4" cols="50" name="description" maxlength="250"></textarea></td>
            </tr>
            <tr>
                <th></th>
                <td><input type="submit" value="Upload"></td>
            </tr>
        </table>
    </form>
</div>
<?php require('inc/footer.php');?>

我尝试更改数据库结构并更改 php.ini

我为 php.ini 更改了以下值

memory_limit=1200M
post_max_size=8000M
upload_max_filesize=2000M

我为大文件得到的错误代码是：

警告：73666615 字节的 POST 内容长度超过第 0 行未知中 68157440 字节的限制

注意：未定义索引：第 35 行 C:\xampp\htdocs\Registration\upload.php 中的视频

注意：未定义索引：第 36 行 C:\xampp\htdocs\Registration\upload.php 中的缩略图

小视频文件是成功的，但仍然对正在发生的事情感到困惑

实际结果应该能够成功上传大视频文件的视频。
