PHP怎么让mysql数据表自动归类?

Jun 23, 2016 pm 02:04 PM

有两个表

商品数据表 goods:title,商品标题。brand,品牌id
id    title                     brand
1   化妆品欧莱雅65号   1
2   化妆品温碧泉75
3   化妆品雅琳娜45
4   化妆品香奈儿45     2
5   化妆品欧诗漫22    

品牌表 brand
id  name
1   欧莱雅
2   香奈儿
3   温碧泉
4   雅琳娜
5   欧诗漫


用PHP和sql语句 让 goods表没brand id的号自动获取品牌id,比如商品表id2后面的brand值为3.不知道怎么做了。哪位给个思路。实际上品牌表里面有几百个品牌,商品名肯定包含了一个品牌名。

遍历goods表中的title ,看是否包含brand中的name在里面,有的话,记下id放入一个新数组中作为title的brand值,楼主可以试下

用了个笨办法实现了,只需要功能,不讲究效率了。。

你去研究下orm吧

笨办法就是。先用substr截取3-6位的字符串。取得诸如“欧莱雅”“香奈儿”之类的品牌名称,再去brand表里面查询对应的brand_id。。前提是。你的3-6位字符串恰好是品牌名。

substr($str,9,9); 由于是中文字符串。 如果品牌刚好是第四个中文字符开始。那么截取9个字符、
foreach($brand_name as $key=> $item){
  $name = substr($str,9,9);
  switch($name){
  case '欧莱雅':
   //do something;
   $brand_name[$key]['brand_id'] = 3;
  break;
  case 'xxx':
}
}
不知道是不是你要的那种。。。

substr($str,9,9); 由于是中文字符串。 如果品牌刚好是第四个中文字符开始。那么截取9个字符、
foreach($brand_name as $key=> $item){
  $name = substr($str,9,9);
  switch($name){
  case '欧莱雅':
   //do something;
   $brand_……
其实每个标题没那么规则的 用多重条件 先遍历品牌 然后 遍历没品牌的商品 然后修改为品牌ID

那foreach循环里修改下。 碰到没有id的在查询。
如果商品名称不规则。则用preg_match 正则查询出需要的数据。 逻辑你应该清楚。编码的事相信你可以搞定
