GearmanClient::jobStatus -- gearman_job_status — Get the status of a background job
说明
面向对象风格 (method):
public GearmanClient::jobStatus
( string $job_handle
) : array
Gets the status for a background job given a job handle. The status information will specify whether the job is known, whether the job is currently running, and the percentage completion.
参数
job_handle- 由 Gearman 服务器指派的工作句柄。
返回值
An array containing status information for the job corresponding to the supplied job handle. The first array element is a boolean indicating whether the job is even known, the second is a boolean indicating whether the job is still running, and the third and fourth elements correspond to the numerator and denominator of the fractional completion percentage, respectively.
范例
Example #1 Monitor the status of a long running background job
<?php/* create our object */$gmclient= new GearmanClient();/* add the default server */$gmclient->addServer();/* run reverse client */$job_handle = $gmclient->doBackground("reverse", "this is a test");if ($gmclient->returnCode() != GEARMAN_SUCCESS){ echo "bad return code\n"; exit;}$done = false;do{ sleep(3); $stat = $gmclient->jobStatus($job_handle); if (!$stat[0]) // the job is known so it is not done $done = true; echo "Running: " . ($stat[1] ? "true" : "false") . ", numerator: " . $stat[2] . ", denomintor: " . $stat[3] . "\n";}while(!$done);echo "done!\n";?>
以上例程的输出类似于：
Running: true, numerator: 3, denomintor: 14 Running: true, numerator: 6, denomintor: 14 Running: true, numerator: 9, denomintor: 14 Running: true, numerator: 12, denomintor: 14 Running: false, numerator: 0, denomintor: 0 done!
