thinkphp操作数据库

1.实现or操作：

$where=array(

'city'=>array('like',array('%'.$_GET['city'].'%'));

'hangye'=>array('like',array('%'.$_GET['hangye'].'%'));

);

2.实现既有or又有and的操作

$where['id']=array('neq',$_GET['id']);

$where['_string']="(city like '%".$_GET['city']."%) or (hangye like '%".$_GET['hangye']."%')";

或者

$where['city']=array('like','%'.$_GET['city'].'%');

$where['hangye']=array('like','%'.$_GET['hangye'].'%');

$where['_logic']='or';

$map['_complex']=$where;

$map['id']=array('gt',1);
