Tp5 常用 比较字符

1.数据库 where 条件表； 参考 http://blog.youkuaiyun.com/haibo0668/article/details/78203170

eq = $map['id'] = array('eq',100); 等效于：$map['id'] = 100;
neq != $map['id'] = array('neq',100); id != 100
gt > $map['id'] = array('gt',100); id > 100
egt >= $map['id'] = array('egt',100); id >= 100
lt < $map['id'] = array('lt',100); id < 100
elt <= $map['id'] = array('elt',100); id <= 100
like like $map<'username'> = array('like','Admin%'); username like 'Admin%'
between between and $map['id'] = array('between','1,8'); id BETWEEN 1 AND 8
not between not between and $map['id'] = array('not between','1,8'); id NOT BETWEEN 1 AND 8
in in $map['id'] = array('in','1,5,8'); id in(1,5,8)
not in not in $map['id'] = array('not in','1,5,8'); id not in(1,5,8)
and（默认） and $map['id'] = array(array('gt',1),array('lt',10)); (id > 1) AND (id < 10)
or or $map['id'] = array(array('gt',3),array('lt',10), 'or'); (id > 3) OR (id < 10)
xor（异或） xor 两个输入中只有一个是true时，结果为true，否则为false，例子略。 1 xor 1 = 0
exp 综合表达式 $map['id'] = array('exp','in(1,3,8)'); $map['id'] = array('in','1,3,8');

多条件可用 $db->where()->where() 组合使用
