在ThinkPHP中，where方法可传入where数组条件，现在需要两个where数组条件之间使用or逻辑执行sql查询，也就是：
$where["xx"]=3;
$where["yy"]=9;
$condition["ww"]=33;
$condition["zz"]=99;
现在需要条件是$where or $condition,ThinkPHP中如何表达呢？
这里用到ThinkPHP的组合查询：
$User = M("User"); // 实例化User对象
$map["id"] = array("neq",1);
$map["name"] = "ok";
$map["_string"] = "status=1 AND score>10";
$map["_logic"] = "OR";
$User->where($map)->select();
这里$map[‘_string’]貌似只能传字符串形式，不能传数组，这里希望两个条件都是数组，有两个办法，一个是把数组自己拼接成字符串，另一个办法使用buildSql方法得到其中一个条件下生成的sql，用正则提取其中需要的sql语句。
以下示例是第二个方法：
private function wait_handle_nums($bo_seller_id){
$where_90 = array();
$where_90["bo_deal_status"] = 85;
$where_90["bo_last_modify"] = array(array("gt",date("Y-m-d H:i:s",strtotime("-14 days"))),array("lt",date("Y-m-d H:i:s",strtotime("-13 days"))));
$where_90["bo_seller_id"] = $this->uid;
$where_90 = M("back_order")->where($where_90)->buildSql();
$where_90 = strstr($where_90,"WHERE");
$preg_match = preg_match("/WHERE(.*)/", $where_90, $matches);
if($preg_match){
$where_90 = $matches[1];
$where_90 = "(".$where_90;
}
$where = array();
$where["bo_deal_status"] = 62;
$where["bo_last_modify"] = array(array("gt",date("Y-m-d H:i:s",strtotime("-3 days"))),array("lt",date("Y-m-d H:i:s",strtotime("-2 days"))));
$where["bo_seller_id"] = $this->uid;
$map["_complex"] = $where;
$map["_string"] = $where_90;
$map["_logic"] = "OR";
$field = "COUNT(*) as refund_nums,bo_seller_id";
$re = M("back_order")->where($map)->field($field)->find();
return $re["refund_nums"];
}
得到的执行的sql语句是：
SELECT COUNT(*) as refund_nums,`bo_seller_id`
FROM `js_back_order`
WHERE ( ( `bo_deal_status` = 62 ) AND ( (`bo_last_modify` > "2015-07-10 08:48:20") AND (`bo_last_modify` < "2015-07-11 08:48:20") ) )
OR
( ( ( `bo_deal_status` = 85 ) AND ( (`bo_last_modify` > "2015-06-29 08:48:20") AND (`bo_last_modify` < "2015-06-30 08:48:20") ) ) )
两个where条件直接OR.
