Scheduler

Schedules task execution.

A scheduled task is a callback that should be executed every so often (such as daily, weekly, monthly, etc.). They are registered by extending Tasks.

Tasks are executed when the core:archive command is executed.

Examples

Scheduling a task

class Tasks extends \Piwik\Plugin\Tasks
{
    public function schedule()
    {
        $this->hourly('myTask');  // myTask() will be executed once every hour
    }
    public function myTask()
    {
        // do something
    }
}

Executing all pending tasks

$results = $scheduler->run();
$task1Result = $results[0];
$task1Name = $task1Result['task'];
$task1Output = $task1Result['output'];

echo "Executed task '$task1Name'. Task output:\n$task1Output";
