PHP Program :

  
 <?php  
 // www.beginer2cs.blogspot.com 
 $ip_address = $_SERVER['REMOTE_ADDR'];  //get ip address (inbuilt function in php )
 echo "your ip address is ".$ip_address;   //print ip
 ?>  

Since I run this code at localhost that is  why my localhost ip  was printed 

But if this code is implemented at any page of any website and you gonna open that page your IP address is fetch . and you are no more anonymous . that is why when you open any website using proxy sites  IP address of proxy site is send to website owner not yours

Best example is open  whatismyip  and it will show you your IP address now again open using a proxy site you can see, It shows IP address , It is not your's .basically it is ip address of proxy server .

Thanks have a NIce Day !!!
