PDO return empty object?

Question

PHP

I'm trying to connect to a database.

$pdo = new \PDO("mysql:host=localhost;dbname=database", "user", "password");

Everything connects fine on the localhost, but if you connect to another database on a different hosting, it returns an empty object.
Moreover, if you try to connect to the database through mysqli, then everything works fine.

Answer 1

It seems to me that there is an error in the syntax or you are setting different connection parameters (typo or inattention). It cannot be that mysqli connects with the same parameters, but PDO does not.
