Mysql-thinkphp queries a field and queries the number of times each value of the field appears.

M ($ table)-> field ('field, count (field) ')-> group ('field')-> select ()

Don't be discouraged
Just get familiar with SQL and it has nothing to do with thinkPHP.

Select field, count (field) from table

Select field, count (field) as ct from (select field from field) as tb group by field order by field; I do not know if yes, test it by myself

Select field, count (field) from table group by field;
SQL GROUP
