The third parameter is somewhat confusingly named; it would probably be better described as "$set_state". If true, it sets the bit to 1. If false, it sets the bit to 0. Default is true. <?php $num = gmp_init(1); gmp_setbit($num, 1); echo 'gmp_setbit(1, 1): '.gmp_strval($num, 2)."\n"; // 11 $num = gmp_init(1); gmp_setbit($num, 1, true); echo 'gmp_setbit(1, 1, true): '.gmp_strval($num, 2)."\n"; // 11 $num = gmp_init(1); gmp_setbit($num, 0, false); echo 'gmp_setbit(1, 0, false): '.gmp_strval($num, 2)."\n"; // 0 ?> |
