使用PHP codeigniter以PDF格式下载网页

There are many ways to do this. You can do this on the server side or you can use html5 or a jquery plugin to do this on the client side.

If you're doing it on the server side use a php library such as dompdf or tcpdf and create the file on the server and make it downloadable using proper headers.

If you're doing it on the client browser use a js plugin like jspdf. There are pros and cons on both methods.

You have to use third party tools like tcpdf to convert your html into pdf document.

it is simple to convert your web-page into pdf format.

you can use mPDf or you can use phantomjs
