我正在开发一个 PHP 上传脚本，它允许上传 .mp3 文件等.我创建了一个数组，它指定了允许的文件类型，包括 mp3，并将最大上传限制设置为 500MB:
I'm working on a PHP upload script which allows .mp3 file uploads amongst others. I've created an array which specifies permitted filetypes, including mp3s, and set a maximum upload limit of 500MB:
// define a constant for the maximum upload size
define ('MAX_FILE_SIZE', 5120000);
// create an array of permitted MIME types
$permitted = array('application/msword', 'application/pdf', 'text/plain', 'text/rtf', 'image/gif', 'image/jpeg', 'image/pjpeg', 'image/png', 'image/tiff', 'application/zip', 'audio/mpeg', 'audio/mpeg3', 'audio/x-mpeg-3', 'video/mpeg', 'video/mp4', 'video/quicktime', 'video/x-ms-wmv', 'application/x-rar-compressed');
到目前为止，在测试中，所有指定的文件类型都已成功上传，但由于某种原因，它出现了 .mp3 错误.正如您在上面看到的，我已经包含了音频/mpeg、音频/mpeg3 和音频/x-mpeg-3，但它们似乎都没有什么不同.
So far in testing all specified filetypes have been successfully uploaded but for some reason it comes up with an error for .mp3. As you can see above I've included audio/mpeg, audio/mpeg3, and audio/x-mpeg-3 but none of them seem to make a difference.
有人可以提出问题所在并指出允许上传 .mp3 所需的音频类型吗?
Can someone suggest what the problem could be and also indicate which audio type is the one needed to allow .mp3 uploads?
谢谢
更新:我用来检查文件的代码如下:
Update: The code I'm using to run the check on the file is as follows:
// check that file is within the permitted size
if ($_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.";
}
我得到底部 else 结果告诉我文件大小错误或扩展名不被允许.
I'm getting the bottom else result telling me either the file size is wrong or the extension isn't allowed.
更新 2:我已经运行了 _FILES 数组的 print_r，希望能提供更多信息.结果是:
Update 2: I've run a print_r of the _FILES array to hopefully provide a little more info. The results are:
数组([文件上传] => 数组([名称] => 数组([0] => 莫扎特.mp3[1] =>[2] =>)
Array ( [file-upload] => Array ( [name] => Array ( [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
)
)
)
MAX_FILE_SIZE 是以字节为单位的值
MAX_FILE_SIZE is a value in Bytes
5120000 不是 500 MB.我估计是5MB.
5120000 is not 500 MB. It's 5MB by my reckoning.
您还需要检查您没有超过 php.ini 文件中的post_max_size"和upload_max_size"变量
You'll also need to check that you're not exceeding the "post_max_size" and "upload_max_size" variables in your php.ini file
其次，mp3 可以是以下任何一种 mimetypes
Secondly, an mp3 can be any of the following mimetypes
