will $_POST be able to retrieve the variable?

No, you need to do something like:

* * * * * php -f /wwwroot/htdocs/ping.php -- 5

Then you can use the $argv array to access the 5.

You can do the query string method kind of like you wanted, but the actuall command you'd being calling needs to be some kind of web-browser type program like curl.

RE: cron tab help
I need my php file to write to my crontab file and then execute it. It writes to the file but it just doesn't run it. This is what i tried. The exec() doesn't seem to work

php Code:
Original - php Code 
  1.  
  2. $sid = 30;
  3. $cron = "*/1 * * * * /wwwroot/htdocs/egs/variables.php '$sid'";
  4.  
  5. $handle = fopen("/etc/$sid", "a+");
  6. fwrite($handle, "$cronn");
  7. fclose($handle);
  8.  
  9. exec("/etc/crontab -r");
  10. exec("/etc/crontab $sid");
