I now to ways to detect weather php script runs in cli or web server mode:
if (defined(\'STDIN\'))
or:
if (isset($argc))
Neither. Check the value returned from php_sapi_name()
.
$_SERVER['REQUEST_METHOD'] won't be set, due to the lack of a HTTP request. I think defined( 'STDIN' ) or isset( $argc ) are reliable too, though. If it was up to me, I'd probably go with the defined( 'STDIN' ), as I can imagine someone accidentally setting a value to $argc.
The php_sapi_name function above seems to be another (the most reliable?) way of determining this, although I do think it'd be a good idea to read all the gotcha's: mind that different servers will give different answers.
