Whats the difference?

Just curious to what the difference is between these. When I code, I like to tear mods apart to see how they work and basically create mine off of what I learned from breaking it down. But I saw this and it had me wondering, lol.

THIS is what I use in my modifications:

PHP Code:

{
    print_no_permission();
} 


Then today, I saw this while breaking one down

PHP Code:

{
    print_no_permission();
    exit;
} 


What's the difference? Obviously besides the exit;, but does it change anything different? Which is the proper way (First or second one)?
