调用文件下载头后的PHP调用函数

Question

I have a function creating a file for download like so:

header("Content-type: application/octet-stream");
header("Content-disposition: filename=file.csv");
print 'hello hello';
exit;

$this->nextFuntion();

I need the "nextFunction" to be called after the save dialogue pops up, I've seen various methods around here but they all have to do with header('location:') feature. Basicly the page where the function is called contains the data that goes inside the file. the "nextFunction" will erase the data form the page and return a message etc.

But the best I can do is get the download to work and no function.

Answer 1

Split this into two scripts. The first will call the function, and then redirect to the second (via a META refresh or the like) which will be responsible for sending the file to be downloaded.
