Mpdf

mPDF is a PHP library that transforms UTF-8 encoded HTML and CSS into formatted PDF documents. It serves as a PDF generation engine and document architect capable of converting web pages and HTML forms into professional files.

The project is distinguished by its multilingual rendering capabilities, providing comprehensive support for bidirectional text, right-to-left scripts, and CJK languages using Unicode font embedding and OpenType layout processing. It further enables professional print-ready design through advanced color modeling in CMYK, precise page dimensioning, and compliance with PDF/A and PDF/X archiving standards.

The library covers a broad range of document layout and interactivity features, including the generation of interactive forms, bookmarks, and searchable indexes. It provides detailed controls for page templates, headers and footers, and complex tabular data rendering. Additional capabilities include PDF encryption, font subsetting for file size optimization, and the ability to import external PDF pages as templates.

The system integrates with PSR-3 compliant logging to track internal events and execution errors.
