Why does an error occur when connecting to postgresql?

Question

PostgreSQL

I connect to the database:
$connection = new PDO('pgsql: host = ***; port = ***; dbname = ***', '***', '***');

I get this result:
#0: PDO->__construct(string, string, string)

What does this error mean and how can I fix it?

Answer 1

The problem was that on the remote database server where the connection led, access permissions were not correctly set. And the error was not visible, because there was a crooked encoding of the response (apparently that's why it was not displayed). I checked the error like this - I tested the connection from the console - there was also a crooked encoding, but there were also Latin characters by which we managed to recognize the error.
