What is the better way of getting the IP address in PHP:
getenv(\'REMOTE_ADDR\');
or,
$_SERVER[\'REMOTE_ADDR\'];

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.
