How to send schedule emails using php without cron job

I want send schedule mails using my php website, I don't want to use cron job because shared hosting environments might not provide all the functions.

So how can I send schedule mails with my site. Please let 开发者_如何学运维me know.

Thanks in advance, Laxmilal Menaria

The purpose of this website is to allow website administrators without cronjob service on their own host, run cronjobs.

It claims to be free service although I haven't tried it.

You can send emails using visitor hits. Write somewhere (db) the last time you runned job.

$now = time();
if ($now > $last_sent_time + 3600) {
  // code that sends emails
  // goes here ....... 

  set_last_sent_time($now);
}

I think you got the idea. You should put this code on every request to site. The example sends emails every hour.
