我正在开发一个PHP上传脚本,允许.mp3文件上传等.我创建了一个数组,指定允许的文件类型,包括mp3,并设置最大上传限制为500MB：

// define a constant for the maximum upload size
define ('MAX_FILE_SIZE', 5120000);

// create an array of permitted MIME types
$permitted = array('application/msword', 'application/pdf', 'text/plain', 'text/rtf', 'image/gif', 'image/jpeg', 'image/pjpeg', 'image/png', 'image/tiff', 'application/zip', 'audio/mpeg', 'audio/mpeg3', 'audio/x-mpeg-3', 'video/mpeg', 'video/mp4', 'video/quicktime', 'video/x-ms-wmv', 'application/x-rar-compressed');

到目前为止,在测试中所有指定的文件类型都已成功上传,但由于某种原因,它会出现.mp3的错误.正如你在上面看到的那样,我已经包含了audio / mpeg,audio / mpeg3和audio / x-mpeg-3,但它们似乎没有任何区别.

有人可以建议问题是什么,并指出哪个音频类型是允许.mp3上传所需的音频类型？

谢谢

更新：我用来运行文件检查的代码如下：

// check that file is within the permitted size
        if ($_FILES['file-upload']['size'][$number] > 0 || $_FILES['file-upload']['size'][$number] <= MAX_FILE_SIZE) {
            $sizeOK = true;
        }

        // check that file is of an permitted MIME type
        foreach ($permitted as $type) {
            if ($type == $_FILES['file-upload']['type'][$number]) {
                $typeOK = true;
                break;
            }
        }

        if ($sizeOK && $typeOK) {
            switch($_FILES['file-upload']['error'][$number]) {
                case 0:
                    // check if a file of the same name has been uploaded
                    if (!file_exists(UPLOAD_DIR.$file)) {
                        // move the file to the upload folder and rename it
                        $success = move_uploaded_file($_FILES['file-upload']['tmp_name'][$number], UPLOAD_DIR.$file);
                    }
                    else {
                        // strip the extension off the upload filename
                        $filetypes = array('/\.doc$/', '/\.pdf$/', '/\.txt$/', '/\.rtf$/', '/\.gif$/', '/\.jpg$/', '/\.jpeg$/', '/\.png$/', '/\.tiff$/', '/\.mpeg$/', '/\.mpg$/', '/\.mp4$/', '/\.mov$/', '/\.wmv$/', '/\.zip$/', '/\.rar$/', '/\.mp3$/');
                        $name = preg_replace($filetypes, '', $file);
                        // get the position of the final period in the filename
                        $period = strrpos($file, '.');
                        // use substr() to get the filename extension
                        // it starts one character after the period
                        $filenameExtension = substr($file, $period+1);
                        // get the next filename    
                        $newName = getNextFilename(UPLOAD_DIR, $name, $filenameExtension); 
                        $success = move_uploaded_file($_FILES['file-upload']['tmp_name'][$number], UPLOAD_DIR.$newName);
                    }
                    if ($success) {
                        $result[] = "$file uploaded successfully";
                    }
                    else {
                        $result[] = "Error uploading $file. Please try again.";
                    }
                    break;
                case 3:
                    $result[] = "Error uploading $file. Please try again.";
                default:
                    $result[] = "System error uploading $file. Contact webmaster.";
            }
        }
        elseif ($_FILES['file-upload']['error'][$number] == 4) {
            $result[] = 'No file selected';
        }
        else {
            $result[] = "$file cannot be uploaded. Maximum size: $max. Acceptable file types: doc, pdf, txt, rtf, gif, jpg, png, tiff, mpeg, mpg, mp3, mp4, mov, wmv, zip, rar.";
        }

我得到了底部的其他结果告诉我文件大小错误或者不允许扩展名.

更新2：
我运行了_FILES数组的print_r,希望能提供更多信息.结果是：

排列
(
    [file-upload] =>排列
        (
            [name] =>排列
                (
                    [0] => Mozart.mp3
                    [1] =>
                    [2] =>
                )

        [type] => Array
            (
                [0] => audio/mpg
                [1] => 
                [2] => 
            )

        [tmp_name] => Array
            (
                [0] => /Applications/MAMP/tmp/php/phpgBtlBy
                [1] => 
                [2] => 
            )

        [error] => Array
            (
                [0] => 0
                [1] => 4
                [2] => 4
            )

        [size] => Array
            (
                [0] => 75050
                [1] => 0
                [2] => 0
            )

    )

)

解决方法:

MAX_FILE_SIZE是字节值

5120000不是500 MB.据我估算,这是5MB.

你还需要检查你的php.ini文件中是否没有超过“post_max_size”和“upload_max_size”变量

其次,mp3可以是以下任何一种mimetypes

> audio / mpeg
> audio / x-mpeg
>音频/ mp3
> audio / x-mp3
> audio / mpeg3
> audio / x-mpeg3
> audio / mpg
> audio / x-mpg
> audio / x-mpegaudio
