HTML_ToPDF takes the hassle out of generating a PDF file from a Web page. It will convert any HTML document into a format that will look the same on any platform and printer. It includes support for converting images, using the stylesheets to customize the look of the PDF file, and error handling.
PEAR Session Handler stores PHP4 session information in a database so that it is not only faster to retrieve, but it can (generally) handle a much greater load, and is able to be safely shared between machines without significant performance penalty. By default, the PHP session handler uses text files to store session information. While this is fine for smaller sites, it does not scale well and a more robust approach is required for larger sites. Unlike database-specific alternatives, pearsession supports all PEAR databases including Interbase, Informix, mSQL, MySQL, MS SQL Server, PostgreSQL, Oracle, Sybase, and others via ODBC.
