register_block

void register_block(string name, mixed impl, bool cacheable, array or null cache_attrs)

Use this to dynamically register block functions plugins. Pass in the block function name, followed by the PHP function callback 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 and $cache_attrs can be omitted in most cases. See Controlling Cacheability of Plugins' Output on how to use them properly.

        // do some translation with $content
        return $translation;
    }
}
