which is the better way to get the ip

Question

What is the better way of getting the IP address in PHP:

getenv(\'REMOTE_ADDR\'); 

or,

$_SERVER[\'REMOTE_ADDR\'];
         


        

Answer 1

There's no differences between the tho calls. As you can see PHP manual use both method in the same example. There are some cases where you don't have global variables like $_SERVER enabled and you are forced to use getenv(). In my experience i've never seen a server with global variables disabled.
