Does a PHP programmer not have to be a DBA as well?

Question

Database administration

At the moment I want to start learning PHP, but I'm still undecided if I should master the specialization of the DBA, given that this is not at all included in my plans. I'm already familiar with MySQL Server, I know that a PHP programmer should be able to create (I think so), design (I think so again) databases, know how to send database queries to enter new data, select or update existing data, as well as their removal, if necessary. But should I be able to configure the DBMS? It's not for nothing that they came up with a database administrator. What do you think? It’s just that there are many DBMS, it will take a lot of time to learn how to work with them (which I don’t have much due to life circumstances), but learning how to send requests is not so difficult.

Answer 1

in fact, in typical small projects, your little knowledge of mysql will be more than enough to deploy a simple database on pgsql, mssql and, in principle, both oracle and db2 (but you are unlikely to come across them, usually dba always live with these databases)
==
the need for a separate dba usually arises on very loaded and responsible projects, and that was a couple of times on such projects and there dba were part-time everywhere

Answer 2

Just imagine - you come for a probationary period, the employer gives you a typewriter and says install yourself, such and such a linux, put Apache on it, radish and Maria to boot" - and you proudly answer him "PHP programmer is not obliged ..." I can bet that the rest of the phrase you will say on the street.
