Can I please get some opinions on using the php exit() function and whether or not it should be avoided completely or some circumstances where it is ok
It should be used where and when appropriate.
MUST USE CASE: After a header redirect
WHY? Php will continue to run the rest of the code following the redirect if you do not use exit/die after the header call.

Just like @benanamen had said. Use it whenever it’s appropriate. I tend to use die instead of exit simply because die is shorter to type and does exactly what exit does. Way less typing and since these “features” aren’t really functions, you don’t necessarily need to use parentheses unless you want to send out a message. So die; is way shorter and faster to type than exit;.
