I want to run the cron job in server and emails should be sent to the users after the day of registration , a week , 2 weeks. How can I write the script to call cron job.

Answer 1

Firstly create a php script that checks how long has each user been registered. If it's first day, a week or second week of a user then send mail using mail() function or use any php mail library like swiftmailer.

Then run that php script everyday by assigning to crontab. Here's crontab config to run script "At 00:00 every day." http://crontab.guru/#0_0_ _ _*

Answer 2

{   

    $url = "set email function url";
    $cSession = curl_init(); 
    curl_setopt($cSession,CURLOPT_URL,$url);
    curl_setopt($cSession,CURLOPT_RETURNTRANSFER,true);
    curl_setopt($cSession,CURLOPT_HEADER, false); 
    $result=curl_exec($cSession);
    curl_close($cSession);
    echo $result;

}

after that save this file and set that file path on hosting server cron job section i hope this code will you help thanks
