PHP Fog just released better support for Cron Jobs so ENV vars are exported to the job and the command allows arguments. Also, since we "cd" to the document root before running the cron'd command, the command on the cron job page can be shortened to the following:
crawler/crawl.php email@example.com mypassword
Doing it this way also means not having to set the ENV variable.
What's the best way for ThinkUp to determine the app is running on PHPFog? Is there an ENV variable set the app can check for?
