Codeigniter 4 Get Latitude and Longitude From Address Example

Before you start creating the CI project, you need to create Google Maps API for getting address from latitude and longitude.

The getlocation() method helps to invoke the getAddress() function; consequently, it returns the address based on latitude and longitude.

Similarly, the getAddress() method gets address based on lat and long using the Google Maps API.

public function getlocation()
{
    $address = "Chennai India";
    $array  = $this->getAddress($address);
    $latitude  = round($array['lat'], 6);
    $longitude = round($array['long'], 6);           
}
 
function getAddress($address){
  
$lat =  0;
$long = 0;
 
 $address = str_replace(',,', ',', $address);
 $address = str_replace(', ,', ',', $address);
 
 $address = str_replace(" ", "+", $address);

  try {
        $json = file_get_contents('https://maps.google.com/maps/api/geocode/json?address='.$address.'&key=your_api_key');
        $json1 = json_decode($json);
        
        if($json1->{'status'} == 'ZERO_RESULTS') {
        return [
            'latitude' => 0,
            'longitude' => 0
            ];
        }
 
 if(isset($json1->results)){
    
    $lat = ($json1->{'results'}[0]->{'geometry'}->{'location'}->{'latitude'});
    $long = ($json1->{'results'}[0]->{'geometry'}->{'location'}->{'longitude'});
  }
  } catch(exception $e) { }
    return [
    'latitude' => $latitude,
    'longitude' => $longitude
    ];
}
