Answer 1

您需要创建一个cron并调用发送电子邮件的脚本页面。

Answer 2

You need to create a cronjob:

0 1 * * * /path/to/php/file/script.php

This wil run the script.php file every day at 1:00 AM.

# Minute   Hour   Day of Month       Month          Day of Week        Command    
# (0-59)  (0-23)     (1-31)    (1-12 or Jan-Dec)  (0-6 or Sun-Sat)                
    0        1          0             *                *            /usr/bin/find

Answer 3

You need to create a cronjobs and can simplify the script using mysql functions

$getPosts = $db->query("SELECT * FROM posts WHERE DATEDIFF(NOW(), FROM_UNIXTIME('date')) >= 2");

So you fatch data that are posted more or equel than 2 days.
