Get latitude and longitude using google map api - PHP

-
Google provides an API to get latitude and longitude based on the valid address. All we need to do is just pass address to that api. We can able to get response in various format. In below code i’m requesting api to return response a json format. If curl is enabled in your server you can use below function to get latitude and longitude by passing just address. 
function getLocation($address = null){
        $url = 'http://maps.googleapis.com/maps/api/geocode/json?address='.rawurlencode($address).'&sensor=false';
 
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        curl_setopt($ch, CURLOPT_URL,$url);
        $result=curl_exec($ch);
 
        $res = json_decode($result, true);
        if(isset($res['results'][0]['geometry']['location'])){
            return  $res['results'][0]['geometry']['location'];
        }else{
            return false;
        }
}
If curl is not working try this file_get_contents method to get the response. 
function getLocation($address = null){
        $url = 'http://maps.googleapis.com/maps/api/geocode/json?address='.rawurlencode($address).'&sensor=false';
 
        $result = file_get_contents($url);
        $res = json_decode($result, true);
        if(isset($res['results'][0]['geometry']['location'])){
            return  $res['results'][0]['geometry']['location'];
        }else{
            return false;
        }
}

Convert long url to short url using tinyurl api

-
Tinyurl provides us a short and simple service to convert long URL to small(tiny) URL. We can send email without link breakage. Here is the tinyurl api to get shorten url. You can use any of the method. Method 1: Use file_get_contents to fetch tinyurl. echo file_get_contents('http://tinyurl.com/api-create.php?url=http://www.websnippetz.com'); file_get_contents is not working? If your are able to access php.ini file set allow_url_fopen = On or you can use the below method. Method 2: Use cURL (runs faster than file_get_contents) to fetch tinyurl. function get_tiny_url($url) { $url = "http://tinyurl.com/api-create.php?url={$url}"; $ch = curl_init(); $timeout = 5; curl_setopt($ch,CURLOPT_URL,$url); curl_setopt($ch,CURLOPT_RETURNTRANSFER,1); curl_setopt($ch,CURLOPT_CONNECTTIMEOUT,$timeout); $data = curl_exec($ch); curl_close($ch); return $data; } echo get_tiny_url('http://www.websnippetz.com');
