PHP String Slicer

Given a properly nested HTML string it will parse and truncate the string to a specified length while stripping specified properties and tags. This allows you to black-list properties a user may enter to spoof interface elements, JavaScript, or CSS. The primary function is the truncation and ideally from a trusted source. If you need proper HTML validation get a more robust package. I was unable to find a simple solution for truncating arbitrary user text from a trusted source (a CMS back end) and this script was the result. If you make modifications which increase the functionality of this script please let me know. This is made for PHP 4.3 and up. It is a class set up with "fake private" functions (starting with underscores) so has a clean interface provided you respect it by not directly modifying or accessing the state.
