1,多条件模糊查询 
等于：map[‘id′]=array(‘eq′,100);不等于：map[‘id′]=array(‘eq′,100);不等于：map[‘id’] = array(‘neq’,100); 
大于 ：map[‘id′]=array(‘gt′,100);大于@H_478_126@等于：map[‘id′]=array(‘gt′,100);大于等于：map[‘id’]=array(‘egt’,100); 
小于：map[‘id′]=ar@H_419_196@ray(‘lt′,100);小于等于：map[‘id′]=array(‘lt′,100);小于等于：map[‘id’]=array(‘elt’,100); 
模糊查询：map[‘name′@H_502_283@]=array(‘like′,′@H_913_301@thinkphp@H_310_304@between:map[‘name′]=array(‘like′,′thinkPHPbetween:map[‘id’]=array(‘between’,’1,8’); 
map[‘id′]=array(‘between′,array(@H_158_403@‘@H_805_404@1′，‘@H_403_411@8′@H_533_406@）)@H_144_419@；in:map[‘id′]=array(‘between′,array(‘1′，‘8′）)；in:map[‘id’]=array(‘id’,2,3’); 
map[‘id′]=array@H_410_502@(‘notin′,′1,2,3′)@H_218_512@;map[‘id′]=array(‘notin′,′1,3′);data=db(‘user‘)->where($map)->select();

2多条件或查询 
例如 select * From tbl where a like ‘%123%’ or b like ‘%123%’ or c like ‘%123%’ ; 
实现这样的功能，thinkPHP怎么写呢？

where[‘a’]=array(‘like’,”%123%”); 
where[‘b’]=array(‘like’,”%123%”); 
where[‘c’]=array(‘like’,”%123%”);

答案 :where[‘a|b|c’]=array(‘like’,”%123%”);

3多条件分页查询保留参数 
Db::name(“table”)->where(“XXXX”)->paginate(10,false,[‘query‘=>request()->@R_270_1403@]); 
paginate方法的第三个参数
