Note Submitter: sheppard dot daniel at gmail dot com ---- There actually IS an XOR operator symbol. Its the ^ symbol, which strictly speaking in boolean logic should be the OR operator. But in PHP it functions correctly as the XOR operator. <? $a = true; $b = false; $c = ($a ^ $b); echo $c; //returns 1 (boolean true) $a = true; $b = true; $c = ($a ^ $b); echo $c; //returns 0 (boolean false); ?> However, in testing the operator precedence for this I have found unhandled errors in the logic. For instance, the following returns neither true nor false. Perhaps this is not yet fully developed? <? error_reporting(E_ALL); $a = true; $b = true; $d = false; $c = ($a ^ $b || $d); echo $c; //RETURNS NOTHING ?>
