用户指定存储在MySQL数据库中并使用cron作业的提醒时间。 我想每天发送3次通知;根据用户首选时间（使用当地时间）。
我将cron设置为每30分钟运行一次。
<?php
function runCurl($path)
{
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $path);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
$output = curl_exec($ch);
return $output;
curl_close($ch);
}
function getAppUsers()
{
}
function build_batch_request()
{
}
$graph_url = "https://graph.facebook.com/oauth/access_token?client_id=xxx&client_secret=xxx&grant_type=client_credentials&redirect_uri=https://www.example.com/app/";
$result = runCurl($graph_url);
$access_token = json_decode($result)->access_token;
$graph_url = "https://graph.facebook.com/me/notifications?access_token=$access_token&template=Test Message";
$result = runCurl($graph_url);
print_r($result); // for debug only
?>
