thinkphp怎么做模糊查询搜索，完整实例,笨办法

$name = I('post.name');//接收post传值$mail = I('post.mail');$age = I('post.age');if(!empty($name)){$where['name'] = array('like','%'.$name.'%');//封装模糊查询 赋值到数组}if(!empty($mail)){$where['mail'] = array('like','%'.'$mail'.'%');}if(!empty($age)){$where['age'] = $age;}//$where['_logic']='OR';如果查询条件是OR的关系请打开，一般都是AND关系。$test = M('table')->where($where)->select();
//回传查询条件：age到搜索条件；$this->assign('age',$age);
