Lz is recommended to list the table in detail.

SELECT * FROM 'table' WHERE CURRENT_TIME () between' start time 'AND 'End Time ';

You gave the table structure early, and the problem was solved long ago!

Current date now ()

Weekday (now () of today's week ())

Which programs are broadcast today? find_in_set (weekday (now (), 'Week '). Note that your week field name is reserved for mysql.

Current time curtime ()

The time range in which the current time is curtime () between start_time and finish_time

Combined

select * from tbl_name where find_in_set(weekday(now()),`week`) and curtime() between start_time and finish_time

The above is how php judges the content of the current time in a certain time range. For more information, please follow the PHP Chinese network (www.php1.cn )!
