I'm very, very excited to announce that OWASP has chosen to fund development of what Iâ€™m calling "Inspekt" as part of their OWASP Spring of Code 2007. You can read my full proposal at the OWASP SoC Application Page.
The idea behind Inspekt is to provide a comprehensive input filtering and validation library for PHP. Building upon Chris Shiflett's original Zend_Filter_Input implementation
Some of the new features of this library include retrieval and filtering support for multidimensional arrays, a variety of helper methods to reduce code verbosity, compatibility with PHP4 and PHP5, and will be entirely self-contained (yet easily "pluggable").
Check out his full proposal for more details on what direction the project's heading and some sample code to show how it might all work.
