Detect Country using PHP with IP2Location LITE IP-COUNTRY Database

Good afternoon community. I have a PHP code to detect IPv4 and show the country of origin, using the "IP2Location LITE IP-COUNTRY Database".

My PHP code does not read IPv6 correctly. Will there be any way to modify it? I can't find a solution in any forum.

I attach my detection code for IPv4:

class CountryFromIP { private $CountryIPDatabase = 'dbIPv6.CSV';

      public function GetCountryName($ip) { 
        $this->ip = $ip;
        $ip = sprintf("%u", ip2long($ip)); 
                                           
 
        $csvArray = file($this->CountryIPDatabase);
 
        for($i=0; $i<count($csvArray); $i++){ 
            $setCsv = str_replace("\"", "", $csvArray[$i]); 
            $arrayOfLine = explode(',', $setCsv); 
            if($ip >= $arrayOfLine[0] && $ip <= $arrayOfLine[1] ) { 
                return $countryName = $arrayOfLine[3]; 
            } 
        } 
        return false;
    } 
 
     public function PaisSinEspacios() { 
    
        if($countryName = trim(ucwords(strtolower($this->GetCountryName($this->ip))) )) { 
            
            $countryName = str_replace(' ','%20',$countryName);
        }else{
            $countryName = "Pais desconocido"; 
        } 
    } 
} 
$object = new CountryFromIP();
$countryName =  $object->GetCountryName($ip);

I would appreciate any kind of opinion. Best regards.
