The error "PDOException: SQLSTATE[HY000] [2002] Connection refused" is a common error in PHP when trying to connect to a MySQL database. This error typically occurs when the database server refuses the connection. This can be due to a variety of reasons such as incorrect connection details (hostname, port, username, password), the MySQL server not running, or the server being blocked by a firewall.

Example:

<?php

 

try {

    $pdo = new PDO('mysql:host=localhost;dbname=mydb', 'root', 'wrongPassword');

 

    echo 'Connected';

} catch(PDOException $exception) {

    // 

}
