Asset Helper
If you’re anything like me, you’ve been spoiled by the image, stylesheet, and JavaScript helper functions provided by the popular web development frameworks. If you find yourself wishing you could use them on other, simpler PHP sites, Asset Helper can take some of that pain away.
Asset Helper brings Rails-style asset tag helpers to PHP-based sites, giving you file timestamping and asset hosts. Just include it and go.
Colormap
Created out of a need to manipulate Cascading Style Sheet colors programmatically, Colormap provides an easy way to convert HTML colors between hexadecimal, RGB, and named colors. Originally extracted from Hextractor, Colormap is now freely available in your choice of PHP or Ruby.
Form Style Helper
Form Style Helper is a Ruby on Rails helper module that overrides the standard form helpers in order to add helpful CSS classes to your form elements for easier styling. Now you can more easily differentiate between input fields and buttons, radio buttons and checkboxes, and everything else. All standard Rails form helpers are supported.
