如何使用laravel where子句和created_at从数据库中选择

Question

I want to select all the data on a database using laravel db query or Eloquent ORM. So i want all the data that are other than 3 days from the day they where created. Data 'A' is created on 15th i come in on 16th to check, i won't see Data 'A' but i may see others older than 3 days or equal to 3 days. If i come back on the 18th or 19th i should see Data 'A', obviously because it now older than 3 days or equal to. so i wrote this code that is not working below

$users = DB::table('matched_users')->where( 'created_at', '>=',
 Carbon::now()->subDays(3)); 

so can anyone correct this for me.

when i did that it work but it shows both someone that his date is just one day one. so is that not enough code

Data Name - created_at
ozil        21/04/2012 16:09:22
mark        21/04/2012 16:09:22
cyril       22/04/2012 16:19:21

so today is 25/04/2012 if run the query of run the above query as it is i get all the result back.

But if change the >= to <= the result is an empty collection

Answer 1

I guess you mean 'older than 3 days from the day they where created'. In this case the query should look like this:

DB::table('matched_users')->where('created_at', '<=', Carbon::now()->subDays(3)); 

Answer 2

$users = DB::table('matched_users')->whereDate( 'created_at', '<=', Carbon::now()->subDays(3))->get();

是编写代码的正确方法
