Knowing if the script was called from the command line or from the web

[Chen]

How can I know if a PHP script was called from the web or from the command line? I'm guessing I should be looking at $_ENV but really don't know exactly what I'm looking for.

Thanks! 🙂

Think I found my own answer. 🙂 If $SERVER['argc'] == 0 or empty($SERVER['argv']) the script was called from the web, right? If someone can just verify this for me. 🙂

Thanks!

maybe you could use the referrer command? If there's no referrer, the user did not follow a link.

But if server works for you, why not 🙂
