Crontab

[namida]

Hi

I've searched php documentation and can only find a bit of how to create crontab in

http://my.php.net/ignore-user-abort

and I don't understand the code.
It's
$file="/etc/test.cron"; #contains the cronjobs like
0 * * * * php -f /usr/local/httpd/htdocs/php/mail.php /dev/null 2>&1

system("crontab $file 2>&1" #set file into crontab
system("crontab -r 2>&1" #register actual crontab

Basically can anyone explain to me how to make a crontab / automatic execution of SQL statements?

I saw the faq about crontab

so the file test.cron just contain one line which is
0 6 * * * TERM=xterm; export TERM; /usr/bin/lynx -source "

http://www.server.com/path/to/script.php";

1>/dev/null 2>&1 ???

how long will the script actually run?
