dompdf
Dompdf serves as a converter that transforms HTML into PDF format. At its core, it functions as a layout and rendering engine written in PHP, adhering primarily to CSS 2.1 standards. This style-driven renderer is capable of downloading and interpreting external stylesheets, as well as handling inline style tags and the styling attributes of specific HTML elements. Additionally, it accommodates a majority of presentational HTML attributes. Currently, PDF generation is achieved through either PDFLib or a modified version of the R&OS CPDF class, originally crafted by Wayne Munro, with several significant adjustments made to enhance its functionality. To utilize PDFLib with dompdf, the PDFLib PECL extension must be installed. While integrating PDFLib can enhance performance and slightly lessen the memory demands of dompdf, the R&OS CPDF class, albeit marginally slower, removes the need for any external PDF libraries. Dompdf also supports both local and remote external stylesheets accessed via HTTP or FTP. Moreover, it is capable of handling intricate tables, allowing for row and column spans, as well as separate or collapsed border models, along with the ability to style individual cells as needed. This versatility makes dompdf a robust choice for generating PDFs from HTML content.
