內容簡介
Async Background Worker 是一款 WordPress 外掛，詳細資訊請參閱此頁面 https://tonjoo.github.io/async-background-worker/
範例使用
這是什麼？
這是一款 WordPress 背景工作外掛，能夠讓 WordPress 與 beanstalkd 工作隊列互動。
為什麼需要工作隊列？
當我們需要在後台執行非常耗時的工作時，舉例來說，需要將 100,000 行資料匯入 WordPress 資料庫。我們可以將此任務分成多個較小的任務，這樣較為安全。
WP-CLI
確定您系統已安裝 WP CLI。

新增工作至隊列
使用 add_async_job 命令將新工作新增至新工作者隊列
$job = new stdClass();
// 要執行的函式
$job->function = 'function_to_execute_on_background';
// 使用者輸入的資料
$job->user_data = array('data'=>'some_data');
add_async_job($job);
實作函式
function function_to_execute_on_background($data) {
// 做一些有用的事
echo "背景工作已成功執行\n";
}
執行 wp background-worker listen
命令
wp background-worker
執行 Async Background Worker 一次。
wp background-worker listen
連續執行 Async Background Worker，這是後台工作者想要的。WordPress 框架在每個迴圈中都會重新啟動。
wp background-worker listen-daemon
連續執行 Async Background Worker 而不重新啟動 WordPress 框架。請注意，如果您使用這種模式，任何程式碼變更都不會反映出來。在更改程式碼時，必須每次重新啟動 Async Background Worker。這樣可以節省記憶體並加快速度。

Sample Usage
What is it ?
WordPress background worker plugin that enable WordPress to interact with beanstalkd work queue.
Why we need a worker ?
We can run a very long task in the background, for example we need to import 100.000 row into WordPress databases. Instead of doing the 100.000 import in one job, we can separate the job into many smaller job which is safer.
WP-CLI
Make sure you have WP CLI installed on your system

Add job to queue

$job = new stdClass();
// the function to run
$job->function = 'function_to_execute_on_background';
// our user entered data
$job->user_data = array('data'=>'some_data');
add_async_job($job);
Implement function
function function_to_execute_on_background($data) {
//do something usefull
echo "Background job executed successfully\n";
}
Run wp background-worker listen
