Generated code is:

PHP_METHOD(Phalcon_Html_Tag, appendTitle) {

	zval _0$$4;
	zval *title, title_sub;
	zval *this_ptr = getThis();

	ZVAL_UNDEF(&title_sub);
	ZVAL_UNDEF(&_0$$4);

	ZEPHIR_MM_GROW();
	zephir_fetch_params(1, 1, 0, &title);



	if (Z_TYPE_P(title) == IS_ARRAY) {
		zephir_update_property_zval(this_ptr, SL("append"), title);
	} else {
		zephir_get_strval(&_0$$4, title);
		zephir_update_property_array_append(this_ptr, SL("append"), &_0$$4);
		ZEPHIR_INIT_VAR(&_0$$4);
	}
	RETURN_THIS();

}

172 line is ZEPHIR_INIT_VAR(&_0$$4);

Zephir code:

    public function appendTitle(var title) -> <Tag>
    {
        if typeof title === "array" {
            let this->append = title;
        } else {
            let this->append[] = (string) title;
        }

        return this;
    }
