How can the absence of an else branch in a PHP method like SelectPdoMysql impact the functionality of the code?

The absence of an else branch in a PHP method like SelectPdoMysql can impact the functionality of the code by not handling cases where the query execution fails or returns no results. To solve this issue, we can add an else branch to handle these scenarios, such as returning an empty array or throwing an exception. 

function SelectPdoMysql($pdo, $query) {
    $stmt = $pdo->query($query);
    
    if ($stmt) {
        return $stmt->fetchAll(PDO::FETCH_ASSOC);
    } else {
        // Handle query execution failure or no results
        return [];
    }
}
