PDO always connecting? I thought it would only connect when it was required..

[Desdinova]

Tried to put as much info as possible in the title here.

I thought one of the magic things of PDO was that it would actually connect to the database when a query was executed, and not before, hereby saving resources for script calls that don't need the database at all.

However, I just had entered some wrong credentials in a script not using a database, and I got a connection error, which kinda means it's trying to connect when constructing a PDO object 🙁

Is there something I have to set as an argument? Or is this a feature that I should code by myself?

Any help appreciated 🙂

No, PDO creates the connection when the PDO object is constructed (and throws a PDOException with diagnostic info if the connection fails). Otherwise how would it know that the connection details were valid or that the connection was possible? Think of the PDO object as actually representing the connection.

So to control when the connection is established, control when the object is created.

yeah I figured. all right, I had misunderstood that part then.

thanks for your input.
