I'm pretty excited to release a software library for people who program in PHP, called - PDFB Library. PDFB Library makes it very easy for even novice PHP programmers to generate high-quality dynamic Acrobat PDF files. The library allows you to take any PDF file, then overlay text, images, and barcodes (Code 3 of 9, Code 128, Interleaved 2 of 5, and UPC-A), and generate a new PDF dynamically. Obviously non-programmers wouldn't be interested in something like this but for programmers that have to write hundreds of lines of code just to make a decent invoice or packing slip printable, PDFB just might save a lot of time. I'm releasing it for free hoping that there'll be thousands of others like me who would benefit from it.
