WP插件中的异步php代码

Question

Need to make this block of code asynchronous with the rest of the code. Its going to collect the wp posts and send a post request to my url. The plugin should run asynchronously and doesn't hamper the functioning of the wordpress site.

for ($x=0; $x<=n; $x++) {
$data = posts[$x];
$ch = curl_init('http://myurl.com/');
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'ACCEPT: application/json',
'Content-Length: ' . strlen($data))
);

$result = curl_exec($ch);
curl_close($ch);
}

Answer 1

Use Guzzle Package , code sample:

$request = $client->createRequest('GET', ['future' => true]);
$client->send($request)->then(function ($response) {
    echo 'Got a response! ' . $response;
});

Look how can you install it . Also check the RingPHP and Future Responses for some additional information. Actually RingPHP is utilized as the handler layer in Guzzle and at the bottom, the React/Promise is giving the Promises/A support for PHP .

The proper way to process asynchronous requests in WordPress is to use WP-Cron to schedule an event. You can either schedule it to run once, or on an interval. See some guides on setting it up here . The two main functions to check out are wp_schedule_event() and wp_schedule_single_event() .

One thing to keep in mind however is that because your code is only running when there is a request, if there is low traffic then it's possible that your scheduled event won't run when expected. I wrote an article on my site regarding how you can use crontab in conjunction with WP-Cron to more accurately schedule events: http://justinsilver.com/technology/wordpress/disable-wp-cron-wordpress/ .
