如果超出了我选择的上传限制，则停止上传过程 [英] Stopping the upload process if the upload limit I chose is exceeded

问题描述

到目前为止，我正在开发一个没有任何js的网站项目PHP/APACHE.

I am working on a web site project PHP/APACHE without any js until now.

我发现了各种方法来设置图像到服务器的上传限制.

I found out various ways to set the upload limit of an image to the server.

它们可以工作，但是当我上传一个很大的文件时，您的文件太大"消息之前的延迟太长了.这意味着，如果用户不知道最大为2.4MB，则可能会等一两分钟以上才能看到消息.

They work, but when I upload a very large one, the delay before the message "your file is too big" is from far too long. This means if a user does'nt understand what max 2.4MB is he will be likely to wait more than a minute or 2 before seeing the message.

我的问题是:

如果他尝试传输的图像超出限制，您是否知道自动取消uopload的任何手段?

Do you know any mean to have the uopload automatically cancelled if the image he tries to transfer exceeds the limit ?

非常感谢
