There are 3 records in users table with the same email address.
There are 3 records in users table with the same email address. The problem is when I put * instead of COUNT(user_id) it returns correctly: $query->num_rows gives 3 but when I use COUNT(user_id) then $query->num_rows returns 1 all the time. how can I correct this or where is my problem?

* COUNTs all the rows in the target table whether or not they include NULLs. Syntax diagram - COUNT() function. In the subsequent pages, we have
SELECT COUNT(user_id) AS count_e FROM user WHERE user_email LIKE '$email'.
