Introduction

PDFLib is a modern, driver-based PHP library for manipulating PDF files. It provides a unified, fluent API to handle complex PDF operations by leveraging powerful underlying tools like Ghostscript, Google Chrome, OpenSSL, and PDFtk.

Why PDFLib?

The PHP ecosystem for PDF manipulation is fragmented:

• Generation: dompdf or wkhtmltopdf (legacy).
• Manipulation: fpdip or tcpdf (complex, legacy codebases).
• Previews: spatie/pdf-to-image (limited scope).

PDFLib v3 aims to solve this by being the "One API to rule them all". It decouples the Interface (Fluent API) from the Implementation (Drivers), allowing you to swap backends without changing your code structure.

Core Features

• HTML to PDF: High-fidelity rendering using Chrome/Chromium.
• Manipulation: Merge, Split, Rotate, Watermark, Compress, Encrypt (via Ghostscript).
• Digital Signatures: Sign PDFs securely with X.509 certs (via OpenSSL/TCPDF).
• Interactive Forms: Fill and Flatten AcroForms (via PDFtk).
• Modern DX: PHP 8.1+, Strict Types, Facade-based or Dependency Injection usage.
