逻辑运算符的区别

<?php // "||" has a greater precedence than "or" $e = false || true; // $e will be assigned to (false || true) which is true $f = false or true; // $f will be assigned to false var_dump($e, $f); // "&&" has a greater precedence than "and" $g = true && false; // $g will be assigned to (true && false) which is false $h = true and false; // $h will be assigned to true var_dump($g, $h); ?>

<?php $f = false or true; //is like writting ($f = false ) or true; //and $e = false || true; is the same as $e = (false || true); ?>
