pdo prepared statements with wildcards

This could be an alternative:

$className = '%' . $this->className . '%';
$query->bind_param('s', $className);

It can work with bind param too in following way:

$name = "%$name%";
$query = $dbh->prepare("SELECT * FROM `gc_users` WHERE `name` like :name");
$query->bindParam(':name', $name);
$query->execute();
