How can changing the server address from "localhost" to "127.0.0.1" impact the functionality of Gearman in PHP?

Changing the server address from "localhost" to "127.0.0.1" can impact the functionality of Gearman in PHP if the DNS resolution for "localhost" is not configured correctly. By using the IP address "127.0.0.1" directly, you bypass any potential DNS resolution issues and ensure a direct connection to the local machine. 

$gmclient= new GearmanClient();
$gmclient->addServer('127.0.0.1', 4730);
