funnily enough exit is even listed as a function.
Sure it is: http://us2.php.net/manual/en/function.exit.php
Unless I'm missing a point here or something. :)
Technically, exit is "language construct" and not a function.
It does not require the () at the end.
There are more than a few "language constructs" that are documented
just like functions because 99% of the time, nobody cares that they
aren't functions.
Some common ones:
require
include
isset
exit
die ??? (maybe this one IS a function)
an alias of exit afaict/afaik.
echo
print (used to be a function, maybe still is?)
There are a few places where these not being functions makes a
difference in your life, but for the most part, it doesn't really...
But exit(); makes you look like a newbie for not knowing it's not
really a function and you don't need the ()s unless you want a return
error code.
funny that, I usually use 'exit;' for a clean exit and 'die();' to signify
a shitty exit ... although they are actually indentical functionally - just
my idiosyncrasity ... that said I also so stuff like 'exit(1);' when I really
want to offer a proper exit code. :-/
