This is with ver 1.1.8 provided by Centos7.

First with the installer page building the config.inc.php file. There is a message that:

"Make sure that there are no characters outside the <?php ?> brackets when saving the file."

Yet, there is no '?>' ending tag.

At first I thought that was an error, so I was adding the ?> myself.
Then I noticed other files not having it, like the password plugin. I googled this behavior and found it is RECOMMENDED not to include the ?> ending tag.

So perhaps this message should be changed to tell the user NOT to add an ending ?> tag and cause themselves problems?

Second question.

Can I just add an option to the end of the file. Again with the password plugin, there is:

$config['password_db_dsn'] = '';

Do I have to edit this, or can I simply add to the end of the file:

$config['password_db_dsn'] = 'mysql://postfix:password@localhost/postfix';

Since the file is processed sequentially, the last $config of a variable would be the one in force?

The typical guide says to edit the file with what you need. Seems easier to just append the proper setting.

thanks!
