Why is it not recommended to use the "@" symbol for DB connections in PHP?

Using the "@" symbol for DB connections in PHP is not recommended because it suppresses error messages, making it difficult to troubleshoot and debug connection issues. Instead, it is better to handle errors gracefully by using try-catch blocks to catch and handle exceptions. 

try {
    $db = new PDO("mysql:host=localhost;dbname=mydatabase", "username", "password");
    $db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
} catch(PDOException $e) {
    echo "Connection failed: " . $e->getMessage();
}
