Keep getting notice for use of undefined variables

DoD

I'm currently getting a notice message for all undefined variables i'm using in my script... i get the following notice:

Notice: Undefined variable: right in G:\htdocs\phpBB2\news\news.php on line 10

How can i turn this notice off! If it involves messing with files, which should i mess with?

EDIT: Whoops! I didn't even pay attention to the path. 😃 Editing php.ini would be a lot better solution in this situation.

You can control these notices by adjusting php.ini or .htaccess or with the error_reporting function.

Would be very helpful if i wanted to know if a var is set... which i knew years ago... My problem was a notice caused by the php.ini file.

What level of error reporting to use depends on the application and the developer. I myself always use error_reporting(E_ALL) in conjunction with isset. Mostly to protect against spelling errors.

But, php is a typeless language with no requirement to pre declare or to pre set variables. Many developers chose to just suppress notices.

It appears that DoD was using phpBB. What are you going to do if a piece of third party software throws notices? Maybe switch software, maybe edit the software or maybe just suppress the notices. It's your choice.

And outside of a production environment, those developers are wrong (unlike you, I notice).

DoD, I suggest that you leave error_reporting set at E_ALL, and fix those notices.
Only when it is released in a production website do you set error_reporting to E_ALL & ~E_NOTICE, and set display_errors to off, and log errors instead.

You would also notice that some of phpBB's own security problems arise out of apparently minor problems in validation of input.
