Can these codes be abbreviated below?

Can the following code be abbreviated? Is there a simple way to implement the following code? I think it is too complicated to write this code. if I write data for a month, wouldn't I need to write 30 cases for help, I am a newbie & lt ;? Phpdate_default_timezone_set (PRC); $ c10; $ c20; $ c30; $ c40; $ c50; $ 60; $ c70; $ w & nbsp; date (can these codes be abbreviated below?

------ Solution --------------------
If you get weekly data from the database
Then, set the time data retrieved by $ r ['Date']
$ C = array (0, 0, 0, 0, 0 );
// In The Loop
$ C [date ('W', $ r ['Date'])] ++;
$ C indicates the daily count.

If you get data from the database in January
Then, set the time data retrieved by $ r ['Date']
$ C = array_fill (1, 31, 0 );
// In The Loop
$ C [date ('D', $ r ['Date'])] ++;
$ C indicates the daily count.

What do you want to do?
Can you tell me what your requirements are?

I got all the data for this week from the database, and then determined the number of records each day. for example, today is Thursday, and I got data from the database from Monday to Thursday, then we get the data for Monday, Tuesday, Wednesday, and Thursday respectively. if today is Sunday, I get all the data for this week, and then I get the data for Monday, Wednesday, and Thursday respectively. In the future, it will be extended to the month to get the daily quota.
