This is the most stupid method to add a scheduled plan to scan table data and then send emails.

This can be implemented using PHP. isn't it possible for you to directly insert a database without bypassing PHP? it is not implemented in PHP code yet, so PHP can determine whether the insert is successful and then send an email.

Using mysql to call the php script is not very realistic. sending emails can also be implemented in your code. why do you want to implement it in the database.
