Nút php tải xuống pdf

Để tải xuống PDF từ liên kết HTML bằng PHP với sự trợ giúp của hàm header() trong php. Hàm header() được sử dụng để gửi tiêu đề HTTP thô. Đôi khi, nó muốn người dùng được nhắc lưu dữ liệu, chẳng hạn như PDF đã tạo

cú pháp

header('Content-Disposition: attachment; filename="downloaded.pdf"');

readfile('original.pdf');

.

Ghi chú. Hãy nhớ rằng tiêu đề HTTP() phải được gọi trước khi bất kỳ đầu ra thực tế nào được gửi, bằng thẻ HTML thông thường, dòng trống trong tệp hoặc từ PHP

ví dụ 1. Lưu tệp HTML bên dưới dưới dạng htmllinkpdf. html và lưu tệp PHP dưới dạng tải xuống pdf. php

• Ví dụ dưới đây để minh họa khái niệm tải xuống tệp PDF bằng liên kết HTML
• Tại đây, tệp tải xuống có định dạng PDF nhưng không có bất kỳ nội dung nào hiển thị lỗi khi mở trong bất kỳ ứng dụng nào
• Mã HTML
