On PHP 5.5 you can use the following code for passing context by reference and avoid "Call-time pass-by-reference has been removed":

<?php
$client = new GearmanClient();
$client->addServer();

# Set a function to be called when the work is complete
$client->setCompleteCallback("reverse_complete");

# Use StdClass instead of array
$results = new StdClass();
$results->value = array();

# Add some tasks for a placeholder of where to put the results
$client->addTask("reverse", "Hello World!", $results, "t1");
$client->addTask("reverse", "!dlroW olleH", $results, "t2");

$client->runTasks();

# The results should now be filled in from the callbacks
foreach ($results->value as $id => $result) {
    echo $id . ": " . $result['handle'] . ", " . $result['data'] . "\n";
}

function reverse_complete(GearmanTask $task, StdClass $results)
{
    $results->value[$task->unique()] = array(
        "handle" => $task->jobHandle(),
        "data" => $task->data()
    );
}
?>
