FAQ

Boris doesn't display exceptions or errors when running in my app?

Boris honours your environment. If your application has error handlers installed, they will mask the error. Likewise, if an exception handler is installed, you won't see a backtrace (unless your exception handler displays it).

Since Boris is much more useful when you can see errors in the console, the best thing to do is to disable any exception/error handlers when your application is running inside of Boris.

What about PHP's interactive mode?

PHP's interactive mode does not print the result of evaluating expressions and more importantly, it exits if you type something that produces a fatal error, such as invoking a function/method that does not exist, or an uncaught exception. Boris is designed to be robust, like other REPLs, so you can experiment with things that you know may error, without losing everything.
