bool register_compiler_function ( string name, mixed impl, bool cacheable)
Use this to dynamically register a compiler function plugin.
Pass in the compiler function name, followed by the PHP
function that implements it.
The php-function callback impl can be either (a) a string
containing the function name or (b) an array of the form
array(&$object, $method) with
&$object being a reference to an
object and $method being a string
containing the mehod-name or (c) an array of the form
array(&$class, $method) with
$class being a classname and
$method being a class method of that
class.
cacheable can be omitted in
most cases. See Controlling
Cacheability of Plugins' Output on how to it properly.
