registerTag function

[ly.sit...@gmail.com]

Please explain in detail of registerTag function.

What does it register??
for example: if I add new tag <he>
So, does it recognize the new tag??

I get this code.

$test = function($params)
{
    $value = $params[0];
    return 'Translate: <b>$value</b>';
};

// add a function
RainTpl::registerTag( '({@.*?@})', '{@(.*?)@}', $test );


---- reference ----
    /**
     * Allows the developer to register a tag.
     *
     * @param string $tag nombre del tag
     * @param regexp $parse regular expression to parse the tag
     * @param anonymous function $function: action to do when the tag is parsed
     */
    public static function registerTag($tag, $parse, $function) {
        static::$registered_tags[$tag] = array("parse" => $parse, "function" => $function);
    }

RegisterTag it basically binds a function to a tag, so into your template you can call the function using that tag. 

RegisterTag has 3 parameters, the first is the regular expression to match the tag, the second parameter is the regular expression to match the values into the tag and the third parameter is the function.

Hope this clarify.
