Syntax switch ($this->lexer->lookahead['type']) { case Lexer::T_SELECT: $statement = $this->SelectStatement(); break; case Lexer::T_UPDATE: $statement = $this->UpdateStatement(); break; case Lexer::T_DELETE: $statement = $this->DeleteStatement(); break; default: $this->syntaxError('SELECT, UPDATE or DELETE'); break; }
