PHx (Placeholders Xtended) extends the use of placeholders, template variables and settings tags so you can easily format how the final output should look like. When enabled it plugs into the MODx parser, extends its functionality and as a bonus makes it truly recursive. PHx will also eliminate the need for lesser parameter snippets where youd use them to format a value for display. Great for templating!

Transforming a value is is as easy as adding :modifier.
