Explanation of created functions

getlocation() :- When we pass the address in this function, inside this function we will call the get_longitude_latitude_from_adress() this function with address and it will return latitude and longitude from address.

get_longitude_latitude_from_adress() :- In this function, we will pass the address and this function call google geocode apis and get latitude and longitude from address.

public function getlocation()
{
    $address = "London united state";
    $array  = $this->get_longitude_latitude_from_adress($address);
    $latitude  = round($array['lat'], 6);
    $longitude = round($array['long'], 6);           
}

function get_longitude_latitude_from_adress($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 [
     'lat' => 0,
     'lng' => 0
    ];
 }

 if(isset($json1->results)){
   
    $lat = ($json1->{'results'}[0]->{'geometry'}->{'location'}->{'lat'});
    $long = ($json1->{'results'}[0]->{'geometry'}->{'location'}->{'lng'});
  }
  } catch(exception $e) { }
 return [
 'lat' => $lat,
 'lng' => $long
 ];
}
