How to fix error when connecting to MS SQL?

Question

linux

SW. community, please help. I'm trying to connect to MS SQL c under Linux on php, but it returns an error to me (could not find driver). Tell me what driver it can't find? Or is there a simpler connection without using PDO?
This is my first attempt at interacting php and ms sql, so if it doesn't make it more difficult, tell me in as much detail as possible.

try {

    $DBH = new PDO("mssql:host=$server;dbname=$dbname", '$login', '$pass');

} catch (PDOException $e) {

    echo $e->getMessage();
}

Answer 1

Thank you all for the answers, as it turned out there was no role / permission to the database.
