How to detect ISP with PHP? |

Getting ISP (internet service provider) of a client is possible with using gethostbyaddr function which will attempt to retrieve clien't host by its IP address:
Simple example:
<?php
$hostname = gethostbyaddr($_SERVER['REMOTE_ADDR']);
echo $hostname;But important for you to know is that relying on this is not always possible since the client may be logged in through VPN.
