get geo location via ip address error in class

[gabrielkolbe]

Hi, i am not too familiar with oop, and have would really like to use this class where I get the geo location from a user via the ip address. I get this error because the script is written for php5 and I need to convert it to PHP4. I changed ' Private' for ' Var'  which helps , what do I change ' Public' to ?

 

 

Here's the class.....
<?Php
/**
* This class generates the country name and its flag from its IP address
*
*
* @author Rochak Chauhan
*/

class CountryFromIP {

 private $CountryIPDatabase = 'CountryIPDatabase.txt';
 private $ip = '';

/**
 * Function to validate IP ( please modify it according to your needs)
 *
 * @param $ip - string
 *
 * @return boolean
 */
public function ValdateIP($ip) {
	$ipArray = explode(',',$ip);

	if(count($ipArray) != 4) {
		echo "<font color='red' size='3'> <b>ERROR: </b> Invalid IP</font>";
		return false;
	}
	else {
		return true;
	}
}

/**
 * Function to return Country name from the IPDatabase
 *
 * @param $ip string
 * 
 * @return string - name of the country, false otherwise
 */
public function GetCountryName($ip) {
	$this->ip = $ip;
	$ip = sprintf("%u", ip2long($ip));

	$csvArray = file($this->CountryIPDatabase);

	for($i=0; $i<count($csvArray); $i++) {
		$arrayOfLine = explode(',', $csvArray[$i]);
		if($ip >= $arrayOfLine[0] && $ip <= $arrayOfLine[1] ) {
			return $countryName = $arrayOfLine[2];
		}
	}
	return false;
}

/**
 *  Function to return local path to Country's flag
 *
 * @param $ip - string
 *
 * @return string - local path to flag image
 */
public function ReturnFlagPath() {

	if($countryName = trim(ucwords(strtolower($this->GetCountryName($this->ip))) )) {
                        $countryName = str_replace(' ','%20',$countryName);
		return "flag/$countryName.gif";
	}
	else {
	    return false;
	}
}

}
?>
