PdfParser is a standalone PHP library that provides various tools for extracting data from PDF files. It loads and parses objects and headers, extracts meta data, and extracts text from ordered pages. It supports compressed PDF, MAC OS Roman charset encoding, hex and octal encoding in text sections, and is compliant with PSR-0 (autoloader) and PSR-1 (code styling). Currently, secured documents are not supported.
The Aura.Input package contains tools to describe and filter user inputs from an HTML form, including sub-forms/sub-fieldsets, fieldset collections, an interface for injecting custom filter systems, and CSRF protection. Note that this package does not include output functionality, although the “hints” provided by the Form object can be used with any presentation system to generate an HTML form.
