Expected behavior would be to return bool(false) for NULL values. Reproduce code: --------------- function vdump($value) { ob_start(); var_dump($value); $result = ob_get_contents(); ob_end_clean(); return trim($result); } $db = mssql_connect('servername', 'username', 'password'); mssql_query("CREATE TABLE #demo (bitfield BIT NULL, tinyfield TINYINT NULL)", $db); mssql_query("INSERT INTO #demo (bitfield,tinyfield) VALUES (0, 0)", $db); mssql_query("INSERT INTO #demo (bitfield,tinyfield) VALUES (1, 1)", $db); mssql_query("INSERT INTO #demo (bitfield,tinyfield) VALUES (NULL, NULL)", $db); $result = mssql_query("SELECT * FROM #demo", $db); while ($row = mssql_fetch_row($result)) echo "bit: " . vdump($row[0]) . "\t tiny: " . vdump($row[1]) . "\n"; mssql_query("DROP TABLE #demo", $db); Expected result: ---------------- bit: string(1) "0" tiny: string(1) "0" bit: string(1) "1" tiny: string(1) "1" bit: bool(false) tiny: bool(false) Actual result: -------------- bit: string(1) "0" tiny: string(1) "0" bit: string(1) "1" tiny: string(1) "1" bit: string(1) "0" tiny: bool(false) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=26820&edit=1
