Getting A Variable out of an array?

Hey Everyone,

I am new to PHP and learning a lot but this one has me stumped, I am at variables in an array, and I for the life of me don't understand what I am doing wrong, searched for hours!

I am trying to pull 2 variables out of this array, city and state, and display them on a php page. Any help would be greatly appreciated. I know they are there, because the array is displaying on the page, but I don't want to display the whole thing, just the 2 variables.

<?php
      $ip=$_SERVER['REMOTE_ADDR'];
      print_r(geoCheckIP($ip));
      //Array ( [domain] => dslb-094-219-040-096.pools.arcor-ip.net [country] => DE - Germany [state] => Hessen [town] => Erzhausen )

      //Get an array with geoip-infodata
      function geoCheckIP($ip)
      {
              //check, if the provided ip is valid
              if(!filter_var($ip, FILTER_VALIDATE_IP))
              {
                      throw new InvalidArgumentException("IP is not valid");
              }

              //contact ip-server
              $response=@file_get_contents('http://www.netip.de/search?query='.$ip);
              if (empty($response))
              {
                      throw new InvalidArgumentException("Error contacting Geo-IP-Server");
              }

              //Array containing all regex-patterns necessary to extract ip-geoinfo from page
              $patterns=array();
              $patterns["domain"] = '#Domain: (.*?)&nbsp;#i';
              $patterns["country"] = '#Country: (.*?)&nbsp;#i';
              $patterns["state"] = '#State/Region: (.*?)<br#i';
              $patterns["town"] = '#City: (.*?)<br#i';

              //Array where results will be stored
              $ipInfo=array();

              //check response from ipserver for above patterns
              foreach ($patterns as $key => $pattern)
              {
                      //store the result in array
                      $ipInfo[$key] = preg_match($pattern,$response,$value) && !empty($value[1]) ? $value[1] : 'not found';
              }

              return $ipInfo;
      }

?>

PHP:

 

$ip = geoCheckIP($ip);

echo $ip['state'];
echo $ip['town'];

PHP:

... ?

 

Hey Nico,

Thanks for your reply, when I echo state though, it just says 2?

 

Nevermind, I had it in the wrong spot! Thanks!!

 

A couple of handy hints,
you could of echo'ed the var's from the array like so,

    
$output = geoCheckIP($ip);
echo $output["state"];
echo $output["town"];

PHP:

Or better yet to save some of that regex overhead modify the function itself.

remove or hash out lines 24 and 25 since your not wanting to seek $patterns["domains"] and $patterns["country"]
and modify line 39 return $ipInfo;
to either

return implode(" ",$ipInfo);
return implode(PHP_EOL,$ipInfo);

PHP:

" ", for side by side listing or PHP_EOL, for vertical listing.
Then for call to function simply: echo geoCheckIP($ip);

To change output order swap around line 26 $patterns["state"] and line 27 $patterns["town"] if you wanted to render City before State on the output page.
