Как получить размер видео файла?

Question

Мне нужно, чтобы этот скрипт проверял, является ли загруженный файл видеофайлом или нет, а также слишком велик или не превышает размер файла. Поэтому нужно заменить getimagesize на что-то еще, что получит размер видеофайла. Как я могу сделать это? Какую функцию использовать здесь? getvideosize функция не существует. Вот где я застрял.

<?php 

if($_SERVER["REQUEST_METHOD"] == "POST") 
    { 
        //Check whether the file was uploaded or not without any errors. 
        if(!isset($_FILES["id_verification_video_file"]) && 
$_FILES["id_verification_video_file"]["Error"] == 0) 
        { 
            $Errors = Array(); 
            $Errors[] = "Error: " . $_FILES["id_verification_video_file"] 
["ERROR"]; 
        print_r($_FILES); ?><br><?php 
        print_r($_ERRORS); 
        exit(); 
    } 
    else 
    { 
        //Feed Id Verification Video File Upload Directory path. 
        $directory_path = "uploads/videos/id_verifications/"; 
        //Make Directory under $user in 'uploads/videos/id_verifications' 
        Folder. 
        if(!is_dir($directory_path . $user)) //IS THIS LINE CORRECT ?
        { 
            $mode = "0777"; 
            mkdir($directory_path . $user, "$mode", TRUE); //IS THIS LINE 
        CORRECT ?
        } 

        //Grab Uploading File details. 
        $Errors = Array(); //SHOULD I KEEP THIS LINE OR NOT ?
        $file_name = $_FILES["id_verification_video_file"]["name"]; 
        $file_tmp = $_FILES["id_verification_video_file"]["tmp_name"]; 
        $file_type = $_FILES["id_verification_video_file"]["type"]; 
        $file_size = $_FILES["id_verification_video_file"]["size"]; 
        $file_error = $_FILES['id_verification_video_file']['error']; 

$file = $_FILES["id_verification_video_file"]["name"];

// in PHP 4, we can do:
$fhandle = finfo_open(FILEINFO_MIME);
$mime_type = finfo_file($fhandle,$file); // e.g. gives "video/mp4" 

// in PHP 5, we can do:

$file_info = new finfo(FILEINFO_MIME); // object oriented approach!
$mime_type = $file_info->buffer(file_get_contents($file));  // e.g. gives 
"video/mp4"

 switch($mime_type) {
 case "video/mp4":
 // my actions go here...
}


//  Let's assume that the name attribute of the file input field I have 
used is "id_verification_video_file"

$tempFile =  $_FILES['id_verification_video_file']['tmp_name'];  // path of 
the temp file created by PHP during upload. I MOST LIKELY GOT THIS LINE 
WRONG AT THE END PART. HOW TO CORRECT THIS ?
$videoinfo_array = getimagesize($tempFile);   // returns a false if not a 
valid image file

if ($videoinfo_array !== false) {
$mime_type = $videoinfo_array['mime'];
switch($mime_type) { 

 case "video/mp4":
 // your actions go here...
 move_uploaded_file("$file_tmp", "$directory_path" . "$user/" . 
"$file_name"); //IS THIS LINE CORRECT ?
//Notify user their Id Verification Video File was uploaded successfully. 
echo "Your Video File \"$file_name\" has been uploaded successfully!"; 
exit(); 

    }
}
else {
    echo "This is not a valid video file";
}

 }
    }

Лучшее, что я сделал, выше. Я был бы признателен, если бы вы, ребята, могли добавить правильные строки, где они должны быть, и добавить комментарии, чтобы я мог легко заметить ваши изменения и извлечь уроки из исправлений.

EDIT: Ребята, мне удалось исправить многие вещи в моем текущем обновлении. Но одна новая проблема. Move_uploaded_file () не выполняется. Это почему ? Посмотри. Я на самом деле написал свои вопросы к вам в комментариях моего кода в капитале. Если бы вы любезно ответили на эти вопросы, я был бы признателен, и мы надеемся, что мы сможем закрыть эту ветку как решено как можно скорее.

Я получаю эхо при попытке загрузить файл mp4: Ошибка 3: при загрузке файла id_check.mp4 возникла проблема! Убедитесь, что ваш файл MP4 видео файл. Вы можете попробовать еще раз.

Должен ли я установить права доступа к папке 0644 из 0777? Мне говорят, что я не должен позволять пользователям выполнять какие-либо исполняемые файлы в папке (загрузчики файлов), и поэтому я должен установить для него только для чтения и записи значение «0644». Мне нужно ваше экспертное мнение по этому поводу.
