Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php 'and' is equivalent to &, which is a bitwise operator. && is something else entirely. Previous Comments: ------------------------------------------------------------------------ [2003-11-04 16:00:50] iam at nimajneb dot com Description: ------------ Result of 'and' operator not what is expected. 1 and 0 and 1 => 1? Should be 0. See attached code sample. '&&' operator does function correctly however. Reproduce code: --------------- $primary_err_valid = (($_POST['primary_err'] != "category") and ($_POST['primary_err'] != "separator")); $secondary_err_valid = (($_POST['secondary_err'] != "category") and ($_POST['secondary_err'] != "separator")); $tertiary_err_valid = (($_POST['tertiary_err'] != "category") and ($_POST['tertiary_err'] != "separator")); $error_valid = ($primary_err_valid) and ($secondary_err_valid) and ($tertiary_err_valid); echo "Pri: $primary_err_valid <br>"; echo "Sec: $secondary_err_valid <br>"; echo "Tri: $tertiary_err_valid <br>"; echo "Total Error: $error_valid <br>"; Expected result: ---------------- Pri: 1 Sec: Tri: 1 Total Error: Actual result: -------------- Pri: 1 Sec: Tri: 1 Total Error: 1 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=26122&edit=1
