当上传的文件超过post_max_size php时如何显示错误?

How to display an error when the uploaded files are exceeding post_max_size php?

print_r($_FILES);

当我超过post_max_size

array()

我是从php.net上获得的，但我不理解，也不知道该怎么做，

I got this from php.net but I don't understand it and don't know how to do it,

如果发布数据的大小大于post_max_size，则$ _POST和 $ _FILES个超级全局变量为空.这可以通过各种方式进行跟踪， 例如通过将$ _GET变量传递给处理数据的脚本， 即，然后检查是否 设置了$ _GET ['processed'].

If the size of post data is greater than post_max_size, the $_POST and $_FILES superglobals are empty. This can be tracked in various ways, e.g. by passing the $_GET variable to the script processing the data, i.e. , and then checking if $_GET['processed'] is set.

这是我的表格，

<form action="upload.php" method="post" enctype="multipart/form-data">
  <input type="file" multiple="multiple" name="file[]" />
  <input type="submit" name="upload" value="Submit"/>
</form>

推荐答案

如果$_SERVER['CONTENT_LENGTH']不为零，并且$_POST和$_FILES为空，则上载太大.

If $_SERVER['CONTENT_LENGTH'] is non zero and $_POST and $_FILES are empty, then the upload was too big.
