> $a = $b ^^ $c
You sure? It didn't work for me, and it isn't listed in the PHP manual.
I used:
<?php
var_dump(1 ^^ 0);
var_dump(0 ^^ 1);
var_dump(0 ^^ 0);
var_dump(1 ^^ 1);
?>
to test it and got a syntax error.
I suppose you could use the bitwise one as a bit of a hack, so long as
you 'boolean-ised' both arguments first.
eg $a = (!!$b) ^ (!!$c); // or even $a = !$b ^ !$c; since xor
depends exclusively on both sides being different to each other.
