quoteModifiers can be autoloadedfrom your $plugins_dir (also see: Naming Conventions) or can beregistered explicitely (see: register_modifier). Additionally allphp-functions can be used as modifiers implicitely. (The @count-exampleabove actually uses php's count-function and not a smarty-modifier).Using php-functions as modifiers has two little pitfalls: First:Sometimes the order of the function-parameters is not the desirable one({"%2.f"|sprintf:$float} actually works, but asks for the moreintuitive {For example: $float|string_format:"%2.f"} that is providedby the Smarty distribution). Second: with $security turned on allphp-functions that are to be used as modifiers have to be declaredtrusted in the $security_settings['MODIFIER_FUNCS']-array.
