 You need a valid 'IPGeolocation API key' to use this SDK. [Sign up](https://ipgeolocation.io/signup) here and get your free API key if you don't have one.
 
 ## System Requirements  
+
 Internet connection is required to run this component.
 
 ## Basic Usage
+
 Call method **get_location($apikey, $clientIp)** passing *IP address (optional)* and *API key* as parameters and it will return IP Geolocation API response.
 Note: If you want IP to geolocation for the machine calling IPGeolocation API, leave out the *IP address* parameter.
 
 ```php
 <?php
-    $clientIp = "IP_ADDRESS";
-    $apikey = "YOUR_API_KEY";
+    $clientIp = null;
+    $apikey = "PUT_YOUR_API_KEY_HERE";
     $response = get_location($apikey, $clientIp);
-    $resArr = array();
-    $resArr = json_decode($response);
-    echo "<pre>"; print_r($resArr); echo "</pre>";
+    $json = array();
+    $json = json_decode($response, true);
 
+    echo "<pre>";
+    print_r($json);
+    echo "</pre>";
+
     function get_location($apiKey, $ip = null) {
         $url = "https://api.ipgeolocation.io/ipgeo?apiKey=".$apiKey."&ip=".$ip;
         $cURL = curl_init();
-        
+
         curl_setopt($cURL, CURLOPT_URL, $url);
         curl_setopt($cURL, CURLOPT_HTTPGET, true);
+        curl_setopt($cURL, CURLOPT_RETURNTRANSFER, true);
         curl_setopt($cURL, CURLOPT_HTTPHEADER, array(
-             'Content-Type: application/json',
-             'Accept: application/json'
+            'Content-Type: application/json',
+            'Accept: application/json'
         ));
+        return curl_exec($cURL);
+    }
+?>
+```
+
+### Example
+
+Here is an example to get the geolocation for a list of IP addresses and display the result as a table:
+
+```php
+<style>
+    table, th, tr, td {
+        border: 1px solid black;
+        border-collapse: collapse;
+    }
+
+    th, td {
+        padding: 5px 30px;
+    }
+</style>
 
-        $content = curl_exec($cURL);
-        curl_close($cURL);
-        return $content;
+<?php

+
+    echo "<table>";
+    echo "<tr>";
+    echo "<th>IP</th>";
+    echo "<th>Continent</th>";
+    echo "<th>Country</th>";
+    echo "<th>Organization</th>";
+    echo "<th>ISP</th>";
+    echo "<th>Languages</th>";
+    echo "<th>Is EU?</th>";
+    echo "</tr>";
+
+    foreach($ips as $ip) {
+        $location = get_location($apikey, $ip);
+        $decodedLocation = json_decode($location);
+
+        echo "<tr>";
+        echo "<td>$decodedLocation->ip</td>";
+        echo "<td>$decodedLocation->continent_name ($decodedLocation->continent_code)</td>";
