问题
So I'm trying to both dynamically create a .doc file and have the user download it when he clicks a button.
These are the headers i found to download a file
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
And these are the headers i found to make a a word document
header('Content-type: application/vnd.ms-word');
header('Content-Disposition: attachment; Filename='.$myFile);
I'm just having a hard time just fitting the picture together because they both tasks have a 'Content-Type' header. Do i create the file first, save it, then download it? Or can i do it all (create a doc file and have user download it) in one php file?
回答1:
You only need the "headers found to make a word document." The first set are for a generic streaming download.
回答2:
Your second set of headers are fine. No need for the first. The Content-Disposition header is the one that will typically force a download. (Although, you should be aware that clients can do whatever they want with a file, and you have no direct control over this.)
You can create the file and send it straight to the client without saving it to the server's disk, depending on how you are creating this document.
