Adds a task to be run in parallel with other tasks. Call this method for all the tasks to be run in parallel, then call GearmanClient::runTasks() to perform the work. Note that enough workers need to be available for the tasks to all run in parallel.
A registered function the worker is to execute
Serialized data to be processed
Application context to associate with a task
A unique ID used to identify a particular task
A GearmanTask object or FALSE
if the task could not be added.
<?php # Create our gearman client $gmclient= new GearmanClient(); # add the default job server $gmclient->addServer(); # set a function to be called when the work is complete $gmclient->setCompleteCallback("complete"); # add a task to perform the "reverse" function on the string "Hello World!" $gmclient->addTask("reverse", "Hello World!", null, "1"); # add another task to perform the "reverse" function on the string "!dlroW olleH" $gmclient->addTask("reverse", "!dlroW olleH", null, "2"); # run the tasks $gmclient->runTasks(); function complete($task) { print "COMPLETE: " . $task->unique() . ", " . $task->data() . "\n"; } ?>
The above example will output something similar to:
COMPLETE: 2, Hello World! COMPLETE: 1, !dlroW olleH
<?php $client = new GearmanClient(); $client->addServer(); # set a function to be called when the work is complete $client->setCompleteCallback("reverse_complete"); # Add some tasks for a placeholder of where to put the results $results = array(); $client->addTask("reverse", "Hello World!", &$results, "t1"); $client->addTask("reverse", "!dlroW olleH", &$results, "t2"); $client->runTasks(); # The results should now be filled in from the callbacks foreach ($results as $id => $result) echo $id . ": " . $result['handle'] . ", " . $result['data'] . "\n"; function reverse_complete($task, $results) { $results[$task->unique()] = array("handle"=>$task->jobHandle(), "data"=>$task->data()); } ?>
The above example will output something similar to:
t2: H.foo:21, Hello World! t1: H:foo:22, !dlroW olleH
