If you want to test all job servers you can use the following code:
<?php
// Create our client object
$client= new GearmanClient();
// Add available and unavailable servers
$client->addServers('127.0.0.1:4730,127.0.0.2:4731');
// Test all job servers
$success = @$client->ping('data testing');
if (!$success) {
die('Error: ' . $client->error());
}
// Sending job
echo $client->doNormal('reverse', 'Hello World!');
?>
