Heya,
I wrote my question already on the general list but got no answer. Maybe someone on this list can
help me out.
I was wondering for what reason PHP has weak logic operators. So far I have only used the weak logic
operator 'or' in
the following situation:
foo() or die("nooo");
And it is quite a long time ago I have used it the last time. You could also write the following
instead:
if(!foo()){
die("noooo");
}
I am aware of that one can use 'or' and 'and' as substitute for || and
&& if using brackets in addition:
$a = ( foo() and bar() );
But I do not really see the benefit of writing it this ways.
I think the weak logic operators just add more complexity to the language and hence decrease
maintenance. Moreover they
are a source of confusion (should I use 'or' or || etc.). The situation for the operator
'xor' is even worse than for
'or' and 'and' in my opinion, since it has no short-circuit and one could use ^
instead of xor:
$a = ( foo() xor bar() );
Could be written as follows:
$b = foo() ^ bar();
So I am curious, are there other use cases out there that justify the existence of those operators?
Cheers,
Robert
