note 74720 deleted from language.operators.bitwise by danielc

Note Submitter: don dot hosek at gmail dot com Reason: 0 ---- Don't forget operator precedence. == has a higher precedence than does & so in the cases that you've written if (9 & 8 == 8) echo 'true'; else echo 'false'; is the same as 9 & (8 ==8) which is 9 & true or 9 & 1 which is 1 which is true if (8 & 8 == 8) echo 'true'; else echo 'false'; is the same as 8 & (8 == 8) which is 8 & true or 8 & 1 which is 0 which is false Putting in parentheses is required to cause the bitwise and to take place before the comparison.
