How do I determine whether PHP is running from the console or not?

Question

php -f script.php param1 param2

At the moment, I am just checking whether isset($argv). Is this the best way?

P.S. I also wanted to know if all input parameters are always stored in $argv?

Answer 1

As you can read here Is there any way to know if a php script is running in cli mode? you can use this function:

function is_cli()
{
    return php_sapi_name() === 'cli';
}

Answer 2

Check whether or not a REQUEST_METHOD is set:

/**
 * Check if the site is being visited (in a browser) or run as a program from the 
 * commandline.
 * @return boolean true if the request appears to come from the WWW, false if not.
 */
function is_web_request () {
    return isset($_SERVER['REQUEST_METHOD']);
}
