What is the better way of getting the IP address in PHP:
getenv('REMOTE_ADDR');
or,
$_SERVER['REMOTE_ADDR'];
please tell me the difference, if any, between the two.
getenv() can be used to access any environment variables (PHP simply registers REMOTE_ADDR as an environment variable for the script), while with $_SERVER you obviously only access the contents of the $_SERVER superglobal.
The common approach is to use $_SERVER for this, although it doesn’t really make a difference functionality-wise.
