Mastering PDF with PHP
Mastering PDF with PHP
Create, read and edit PDF files in your PHP applications
About the Book
Welcome to the world of dynamically built PDF documents!
In today's web applications, the Portable Document Format is commonly used to send invoices, reports, tickets, e-books and many other files. Chances are that you are already working in a project that requires processing PDF files.
With this book, you'll save a lot of time by knowing the most popular tools on the market, their features and drawbacks. You'll avoid wasting weeks comparing and hacking a multitude of solutions. This is your guide to achieve great results faster!
My book is not tied to any particular framework, however we might use some components. Users of all frameworks are welcome here, just like people who code plain PHP.
This is a work in progress. I will add more details about every HTML to PDF conversion tool that I know. I will cover advanced features like PDF/A, tagged PDF, and so on.
However, if you buy this book now, you'll get free lifetime updates! And I might raise the price in the future, so hurry up!
