Simple Tutorial Get Geolocation IP With PHP

To get Geo location (country, city, isp, etc.) based on website visitor IP in PHP application can use API from ip-api.com. In this article, I will share how to get geolocation information from site visitors using PHP.

IP-API is a free GEO LOCATION IP service with multiple response formats. In addition to free, its use is also quite easy to apply. However, free facilities have some limitations. IP-API server will automatically be banned IP Addresses if making more than 150 requests per minute. If you need more data from IP-API, you can buy a pro service.

Make a function to get Ip visitors

function get_header_info(){
	$header = array();
	$ipaddress = '';
	if (isset($_SERVER['HTTP_CLIENT_IP']))
		$ipaddress = $_SERVER['HTTP_CLIENT_IP'];
	else if(isset($_SERVER['HTTP_X_FORWARDED_FOR']))
		$ipaddress = $_SERVER['HTTP_X_FORWARDED_FOR'];
	else if(isset($_SERVER['HTTP_X_FORWARDED']))
		$ipaddress = $_SERVER['HTTP_X_FORWARDED'];
	else if(isset($_SERVER['HTTP_FORWARDED_FOR']))
		$ipaddress = $_SERVER['HTTP_FORWARDED_FOR'];
	else if(isset($_SERVER['HTTP_FORWARDED']))
		$ipaddress = $_SERVER['HTTP_FORWARDED'];
	else if(isset($_SERVER['REMOTE_ADDR']))
		$ipaddress = $_SERVER['REMOTE_ADDR'];
	else
		$ipaddress = 'UNKNOWN';

	$header['ipaddress'] = $ipaddress;
	if(isset($_SERVER['HTTP_REFERER']))
	{
		$header['referer']= $_SERVER['HTTP_REFERER'];
	}else
	{
		$header['referer'] ='';
	}
	$header['useragent'] = $_SERVER['HTTP_USER_AGENT'];
	$header['requesturi'] = $_SERVER['REQUEST_URI'];
	return $header;
}

function get_header_info(){

$header = array();

$ipaddress = '';

if (isset($_SERVER['HTTP_CLIENT_IP']))

$ipaddress = $_SERVER['HTTP_CLIENT_IP'];

else if(isset($_SERVER['HTTP_X_FORWARDED_FOR']))

$ipaddress = $_SERVER['HTTP_X_FORWARDED_FOR'];

else if(isset($_SERVER['HTTP_X_FORWARDED']))

$ipaddress = $_SERVER['HTTP_X_FORWARDED'];

else if(isset($_SERVER['HTTP_FORWARDED_FOR']))

$ipaddress = $_SERVER['HTTP_FORWARDED_FOR'];

else if(isset($_SERVER['HTTP_FORWARDED']))

$ipaddress = $_SERVER['HTTP_FORWARDED'];

else if(isset($_SERVER['REMOTE_ADDR']))

$ipaddress = $_SERVER['REMOTE_ADDR'];

else

$ipaddress = 'UNKNOWN';

$header['ipaddress'] = $ipaddress;

if(isset($_SERVER['HTTP_REFERER']))

{

$header['referer']= $_SERVER['HTTP_REFERER'];

}else

{

$header['referer'] ='';

}

$header['useragent'] = $_SERVER['HTTP_USER_AGENT'];

$header['requesturi'] = $_SERVER['REQUEST_URI'];

return $header;

}

Create a function to call the geolocation API from ip-api.com

function geolocation($ip){
	$ch = curl_init('http://ip-api.com/json/'.$ip);  
	curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");                     
	curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);  
	curl_setopt($ch, CURLOPT_CONNECTTIMEOUT ,5); 
	curl_setopt($ch, CURLOPT_TIMEOUT, 10); 
	$xresult = curl_exec($ch);
	$xresult = json_decode($xresult,true);
	return $xresult;
}

function geolocation($ip){

$ch = curl_init('http://ip-api.com/json/'.$ip);

curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

curl_setopt($ch, CURLOPT_CONNECTTIMEOUT ,5);

curl_setopt($ch, CURLOPT_TIMEOUT, 10);

$xresult = curl_exec($ch);

$xresult = json_decode($xresult,true);

return $xresult;

}

Test both functions above using the following code

$header = get_header_info();
echo '<h3>Array from get_header_info function:</h3><br/>';
foreach ($header as $key => $value) {
	echo $key.' => '.$value.'<br/>';
}
echo '<br/>';
$getloc = geolocation($header['ipaddress']);
echo '<h3>Array from geolocation function:</h3><br/>';
foreach ($getloc as $key => $value) {
	echo $key.' => '.$value.'<br/>';
}
