The Builder.com.au website has a new tutorial posted today that looks at the dynamic creation of a web standard (PDF files) inside of a PHP script.
An alternative way of generating PDF files with PHP is using FPDF, a free PHP class containing a number of functions for creating and manipulating PDFs. The key word here is free. You are free to download and use this class or customise it to fit your needs. In addition to being free, it's also simpler to use than PDFlib. The PDFlib needs to be installed as an extension in your PHP package, whereas FPDF can just be included in your PHP script and it's ready to use
They show how to use the FPDF library to make some simple files - setting the title, author, adding images and text, etc. There's even a little bit there at the end about adding new pages to make more complex documents simple.
