Net_Geo Pear Package in PHP

Question

I have installed the Net_Geo pear package on my PHP Server.

This is the code I am using,

getRecord($ip); // output echo "Single IP results:
"; echo "

";
    print_r($results);
    echo "

"; // example array of multiple IPs $arr_ips = array ( gethostbyname("www.google.com"), gethostbyname("www.heise.de"), gethostbyname("www.college.ch") ); // fetch information array from net_geo $results = $net_geo->getRecord($arr_ips); // output echo "Multiple IP results:
"; echo "

";
    print_r($results);
    echo "

"; ?>

But this piece of code is not displaying any results. I think this code is not working at all.

This is the Net_Geo Object

The documentation page of Net_Geo::Net_Geo() says that :

The method accepts two parameters :

bool Net_Geo() ( string $applicationName = '' , string $alternateServerUrl = '' )

And those parameters are :

• string $applicationName - Optional application name to use in UserAgent when polling Netgeo
• string $alternateServerUrl - URL to Netgeo service script, will be set to "http://netgeo.caida.org/perl/netgeo.cgi" unless changed

You are not passing any of those parameters -- which means the default Netgeo service URL is used...

... And if you try to open it ( http://netgeo.caida.org/perl/netgeo.cgi ), you'll see it doesn't work ; my Firefox says it cannot connect to the server.

This probably explains why your code doesn't produce any expected output : if it relies on a geolocalition server, and that server doesn't work anymore...

As a sidenote : according to the index of pear packages in the Networking section, Net_Geo is not maintained anymore, and the last version was released in 2006-03-29 ; which is quite not a good sign...

If you can install PECL packages (you'll probably need to be admin of your server), maybe the GeoIP package would interest you.
