+# IP Geolocation API PHP SDK
+You need a valid IPGeolocation API key to use this SDK. Sign up(https://ipgeolocation.io/signup?plan=1) if you don’t have API key.
 
 ## Quick Start Guide
-  
-  There is a methode get_location($apikey, $clientIp) in below given snippet which takes apiKey and clientIp as parameter and returns the response from ipgeolocation. 
-  
-  All you have to do is replace keyword "YOUR_CLIENT_IP" with your valid client ip and "YOUR_API_KEY" with valid apiKey provided by ipgeolocation. 
-  
-  Note: This snippet requires a valid IPGeolocation API key. Sign up (https://ipgeolocation.io/signup?plan=1) if you don’t have API key. And you may leave YOUR_CLIENT_IP empty.
-  
-```
-<?php
-$clientIp = "YOUR_CLIENT_IP";
-$apikey = "YOUR_API_KEY";
-
-$response = get_location($apikey, $clientIp);
-$resArr = array();
-$resArr = json_decode($response);
-echo "<pre>"; print_r($resArr); echo "</pre>";
-function get_location($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);
+Call method **get_location($apikey, $clientIp)** passing *API key* and *IP address (optional)* as parameters and it will return IPGeolocation API response.
+Note: If you want IP to geolocation for machine calling IPGeolocation API, don't pass the *IP address* parameter.
 
-curl_setopt($cURL, CURLOPT_HTTPHEADER, array(
- 'Content-Type: application/json',
- 'Accept: application/json'
-));
-
- $content = curl_exec($cURL);
