GearmanClient::addTask — Add a task to be run in parallel
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.
Die registrierte Funktion, die der Worker ausführen soll
Serialisierte Daten, die verarbeitet werden sollen
Der Anwendungskontext der mit einem Task verknüpft werden soll
Eine eindeutige ID, die einen bestimmten Task identifiziert
A GearmanTask object or FALSE if the task could not be added.
Beispiel #1 Basic submission of two tasks
<?php
# Create our gearman client
$gmclient= new GearmanClient();
# add the default job server
$gmclient->addServer();
# 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");
# set a function to be called when the work is complete
$gmclient->setCompleteCallback("complete");
# run the tasks
$gmclient->runTasks();
function complete($task)
{
print "COMPLETE: " . $task->unique() . ", " . $task->data() . "\n";
}
?>
Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:
COMPLETE: 2, Hello World! COMPLETE: 1, !dlroW olleH
Beispiel #2 Basic submission of two tasks with passing application context
<?php
$client = new GearmanClient();
$client->addServer();
# 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->setCompleteCallback("reverse_complete");
$client->runTasks();
# The results should now be filled in from the callbacks
foreach ($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());
}
?>
Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:
t2: H.foo:21, Hello World! t1: H:foo:22, !dlroW olleH
