In Doctrine configuration reference (driver) I see pdo_mysql
as a possible value, but not mysql
, which is the one defined by default in Symfony (in DATABASE_URL
).
I have checked that it’s using PDO even though mysql
is defined as driver
in DATABASE_URL
, but I can’t find any reference. Is it an alias of pdo_mysql
?
On the other hand, in the same reference page I see an example with pdo-mysql
, not pdo_mysql
. Is there any sort of transformation of driver
within DATABASE_URL
?
What are then all possible values for driver
in DATABASE_URL
?
