Get Visitor's location and TimeZone
In this post, you will learn how to get a visitor's current location and timezome using the PHP programming language.
For this, we are using the HTML5 Geolocation API. The HTML5 Geolocation API is used to get a visitor's latitude and longitude and helps us to easily trace the visitor's full address (location, city, district, state, pincode ), but this is possible only when the user clicks on the allow button of the notification to share their current location. This notification is basically for privacy reasons.
Here is the simple code written in HTML5, PHP, and JavaScript to get the current visitor's location. For this, we have created two files: index.php and get_location.php. In 'index.php', the getlocation() function gets the visitor's current position, and the visitorLocation() calls the Ajax file 'get_location.php' and passes the latitude and longitude to get the visitor's address. The GoogleMapsTimeZone is used to get Time Zone information for a given latitude and longitude pair.

if(document.getElementById('location').innerHTML == '') {
navigator.geolocation.getCurrentPosition(visitorLocation);
}
} else {
$('#location').html('This browser does not support Geolocation Service.');
}
}
function visitorLocation(position) {
var lat = position.coords.latitude;
var long = position.coords.longitude;
$.ajax({
type:'POST',
url:'get_location.php',
data:'latitude='+lat+'&longitude='+long,
success:function(address){
if(address){
$("#location").html(address);
}else{
$("#location").html('Not Available');
}
}
});
}
</script>
<input type="button" onclick="return getlocation()" value="Get Current Location" />
<div id="container"><p>Your Current Location: <span id="location"></span></p></div>

2. get_location.php
<?php
if(!empty($_POST['latitude']) && !empty($_POST['longitude'])){
require_once ('GoogleMapsTimeZone.php');
//Send request and receive latitude and longitude
$url = 'http://maps.googleapis.com/maps/api/geocode/json?latlng='.trim($_POST['latitude']).','.trim($_POST['longitude']).'&sensor=false';
$json = @file_get_contents($url);
$data = json_decode($json);
$status = $data->status;
if($status=="OK"){
$location = $data->results[0]->formatted_address;
}else{
$location = 'No location found.';
}
$status = $data->status;
if($status=="OK"){
$location = $data->results[0]->formatted_address;
}else{
$location = 'No location found.';
}
// Initialize GoogleMapsTimeZone object
$timezone = new GoogleMapsTimeZone(trim($_POST['latitude']), trim($_POST['longitude']), GoogleMapsTimeZone::FORMAT_JSON);
// Set Google API key
$timezone->setApiKey(YOUR_API_KEY);
$timezone_data = $timezone->queryTimeZone();
if($timezone_data[status] == 'OK') {
$timezoneid = $timezone_data[timeZoneId];
$timezonename = $timezone_data[timeZoneName];
$location .= '<br/>TimeZone: '.$timezoneid;
$location .= '<br/>TimeZone Name: '.$timezonename;
}
echo $location;
}
?>
