How can PHP developers retrieve the IP address of a client using $_SERVER["REMOTE_ADDR"]?

To retrieve the IP address of a client using $_SERVER["REMOTE_ADDR"], PHP developers can simply access the value stored in this superglobal array. This method provides the IP address of the client accessing the PHP script. It is important to note that this method may not always return the accurate IP address due to factors like proxy servers or load balancers.
