@Jason That is fine unless you need to call the script from a remote server via wget.

to make sure normal webusers are not accessing this unless im missing something, just pass and argv value in the command and check for it in the script. As far as i know ARGV can not be POSTED, so only a command line method can pass this value. So only your script and a terminal can call it.

You can use wget and just pass it a secret key to stop others from accessing the script as I have described here: http://blog.simonholywell.com/post/374209271/linux-to-windows-server-migrating-and-securing-your-cron

You would need to use php via the command line, and place the file outside of the home directory. Assuming your home directory is /home/username/web/, /home/username/public_html/ or something similar, you would use something like:

$command = "nohup /usr/local/bin/php -f /home/username/execute.php";


//Then:

@exec( "$command> /dev/null &", $arrOutput );

now hoe do you keep people from directly accessing the file http://www.mysite.com/background_script.php? So that exec() is the only way to run it?

In this case they were.

Normally I would go with php cli:
php -f /path/to/page > /dev/null &

Are the two scripts on different machines? Why not simply call the php CLI from exec?
