After you download file you can check MIME type with mime_content_type() 下载文件后，您可以使用mime_content_type（）检查MIME类型。
It depends on server settings. 这取决于服务器设置。 Also remember that php has so timeout. 还记得php有这么超时。 Maybe it would be better if you use some kind of queue to do it asynchronously. 如果您使用某种队列异步执行它，可能会更好。
It would be better to use readfile() instead of fread() , readfile() won't cause memory problems. 最好使用readfile（）而不是fread() ， readfile()不会引起内存问题。
It is important to turn off output buffering when downloading large files. 下载大文件时，关闭输出缓冲很重要。

Note: readfile() will not present any memory issues, even when sending large files, on its own. 注意：即使单独发送大文件，readfile（）也不会出现任何内存问题。 If you encounter an out of memory error ensure that output buffering is off with ob_get_level(). 如果遇到内存不足错误，请确保使用ob_get_level（）关闭输出缓冲。
