How to connect to Open Server DB via PHP?

Question

PHP

When I go to PHP Adminer, I log in with the data below without any problems. The script itself for some reason does not want to connect to the Open Server database. How to decide?

<?php
$host = 'localhost';
$db   = 'u14215_default';
$user = 'root';
$pass = 'admin';
$charset = 'utf8';

$dsn = "mysql:host=$host;dbname=$db;charset=$charset";
$opt = [
    PDO::ATTR_ERRMODE            => PDO::ERRMODE_EXCEPTION,
    PDO::ATTR_DEFAULT_FETCH_MODE => PDO::FETCH_ASSOC,
    PDO::ATTR_EMULATE_PREPARES   => false,
    PDO::ATTR_PERSISTENT         => true,
];
$pdo = new PDO($dsn, $user, $pass, $opt);

?>

If it is not possible to copy the database access data without errors, then in this case PHP will take the handle and tell you what is wrong. You just need to read the error message.
