Weak logic operators

[Robert Stoll]

Heya,



I was just 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 use it this way. 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 don't really see the benefit of that except that there is no alternative for xor. So the following could make
sense - I have never used it though:

$a = ( foo() xor bar() );



So I am curious, are there other use cases out there?



Cheers,

Robert
