Send email every 24 hours for every topic without using cron

[abs0lut]

I know how to select the members who did not post for every topic.

I need to send an email every 24 hours to the members who did not post for every topic. Could you please help me?

[trq]

Without a scheduler (cron) its going to be quite difficult.

Unless you want to ccess the page every 24 hours and send it.

so, please help me on how to use cron in cpanel. What will I enter in the command field if the path of the script has query string?

http://domain.com/sendemail.php?topicid=1

http://domain.com/sendemail.php?topicid=2 ...

for every topic, I want to send an email to the members who did not post

create one file that goes through all the topics. it will be a LOT easier that way

Did you mean I will include that one file, then if someone visits that topic, the email will be sent. Then what if no one viewed any topics?

[ohdang888]

no...

activitate with a cron_job the file of "send.php";

 

and in that send.php, it will go through all the topics automatically, rather than a individual file for each topic

I have set up a cron task using the cron jobs application in cPanel, I indicated that everyday it should run the following task

http://domain.com/send.php

and I received this email

/bin/sh: http://domain.com/send.php: No such file or directory

could you please help me?

If you don't like cron you could try this:

ignore_user_abort(true);
set_time_limit(0);

do
{
   //Code here
   sleep(86400); //24 hrs
}
while (true);

 

Not tested. I'm sure cron would be much more efficient though, of course I have no experience with it though.

[DeanWhitehouse]

That wont work, maximum exectution time is 30 seconds

[Stephen]

That's why you do:

set_time_limit(0);

[DeanWhitehouse]

One not all hosts allow that , and two he would have to have the script running all the time

You need to actually run the script through the PHP binary.  The shell has no idea how to parse it.  And you don't use the URL of the file, you use the file path.  You'd probably use:

 

0 0 * * * /usr/bin/php /home/yourname/send.php

Well would be good to get have one that does

 

and two he would have to have the script running all the time

When you use ignore_user_abort, it will still run even if the user closes out of the page (I believe). Also using sleep will have it rest for 24 hours to do it again.

 

Cron would be better to do though.

Stephen's right, you can get a script to run 24/7, I made an uploader one time that ran 23.5 hours a day, and only restarted itself with cron to release it's memory and fix if it crashed - and it never crashed. All cron is is a program that runs all the time, there isn't much difference between it and having PHP do it.

 

I would start it with putty and background the process though - we have to do some weird stuff to keep it from dieing when the session was closed.

thanks Stephen, hope it will work.
