PHP 5.4 showing Warning: Illegal string offset error on form that works

[Lberry1000]

I was wondering of anyone can help me. I have 2 of these errors, this one is on: if ( $extra['over_email'] ). Does anyone knows what's wrong with it? I don't know a thing about PHP. I can send the other one after.

     $this->core->db->construct( array(
                                          'select'  => array( 'id', 'name', 'email', 'email_html' ),
                                          'from'    => 'members',
                                          'where'   => array( 'id', '=', $member_id ),
                                          'limit'   => array( 0, 1 ),
                                   )     );

    $this->core->db->execute();

    if ( $this->core->db->get_num_rows() == 1 )
    {
        $mem = $this->core->db->fetch_row();

        if ( $extra['over_email'] )
        {
            $this->core->email->add_recipient( $extra['over_email'] );

            $replacements['MEM_EMAIL'] = $extra['over_email'];
        }
        else
        {
            $this->core->email->add_recipient( $mem['email'] );

            $replacements['MEM_EMAIL'] = $mem['email'];
        }

The error is telling you that at that point in your code, $extra is a string, not an array; so you need to figure out why that is.

And to do that you'll need to know where [font=monospace]$extra[/font] is coming from (somewhere in the function this code was taken from there'd be a statement starting "[font=monospace]$extra =[/font]..."; for some reason the thing in the "..." is a string, not the array it should be).
