PHP - Send an e-mail with a delay of x time

Question

I need send and email after x time using a php code.

I don't want use cronjob. so, this code doesn't works because the php code it's print one time and doesn't change the DOM automatically like js. But I need something like this:

  $today = date('Y-m-d H:i:s');
  $dataorder = date("Y-m-d H:i:s", $order->created);
  $delay_days = 240;
  $senday = date('Y-m-d H:i:s', strtotime( "$dataorder + $delay_days min" ));

   if ($today == $senday) {

    echo "sent";

   } else {

    echo "not yet sent";

   }

Now, I can use js, but I'm not sure if this will work, this php script is an all php page in the backend. so, can I use only php? like use sleep function? or other one

I don't know with is the best way.

(Specifically it is a system of sending emails to remember to leave a commend on the site.)

Thank you

Answer 1

You can achieve this as,

1. As you have data of user\\'s you know on which date a particular user is registered.

2. Write a script which will execute every day & will select all the user's registered 5 days ago. Mail will be sent to all the user's matched for that date.

3. Script will continue to execute till last user is processed for that date.

Answer 2

You can store every email in database table or a temp file and when it's time user action will send pending emails. You can make a ajax request every 10 seconds for example which will send mails to prevent slow loading of page.

Better solution is if you use a cronjob for jobs like this.
