[Solved] Return $data question

Define $message='' before entering the foreach loop.

Is This Correct

PHP Code:

public function display_error_messages($open_tag = '<p>', $close_tag = '</p>') {

        if (isset($this->error_message)) {

            $message = "";

            foreach($this->error_message as $msg) {
                $message .= $open_tag . $msg . $close_tag;
            }


        }

        return $message;

    } 


There's only one rule - please don't tell anyone to go and read the manual.  Sometimes the manual just SUCKS!
