UverseWiki is a modular open source PHP framework designed for text processing. Unlike most existing solutions, it is not regular expression-based but instead uses a recursive descent parser to build a document object model. After the parsing stage has been finished and the DOM is produced, the original source is discarded and all operations are performed on the document tree instead: nodes can be altered, serialized, or rendered into a particular format (such as HTML or RTF). The wiki syntax is language-neutral and the processing itself is carried out in UTF-8.
GIF Animation Resizer is a class that can resize animations in files of the GIF format. It can take an animated GIF image file and extract its frames to files into a temporary directory. The class resizes the extracted images and rebuilds the animation into a new file in the GIF format.
FuzzyIndex indexes text for performing fuzzy searches using PHP and SQLite. It can process a list of text strings and build a database which indexes snippets of those strings and the locations where they appear. The class can also search for given keywords and returns the locations of the indexed strings where the best-matching text appears. It uses SQLite to store the indexed text database, but the class can be extended to use a different database type. It uses certain heuristics to extract the snippets from the indexed text. These heuristics are implemented as separate classes which can be used interchangeably.
phpLogin is a user login and authentication module for the phpNova framework. It contains all user authentication-related tasks and UI. Dependencies include: phpSession, phpHash, and phpSQL. This module is part of the phpNova framework for PHP, which is currently in the alpha stages of development.
PHPDF is a toolkit for creating PDF reports in PHP. It takes care of dividing your data into pages, adding page headers and footers if desired. Widow/orphan protection is also built in. It loads quickly and has a low memory footprint. It has a built-in PDF document writer, so it doesn't need an external library.
