I modified the code to work with new versions of PHP.
PHP:
<?php 
$username = "DB_USER";
$password = "DB_PASSWORD";
$hostname = "DB_HOST"; 
$dbName = "DB_NAME";
// Fill your own ips 
$white_list = array('59.113.11.149','29.143.30.23','127.0.0.1');
//connection to the database
$con = mysqli_connect($hostname,$username,$password,$dbName);
 
// Check connection
if (mysqli_connect_errno())
  {
  echo "Failed to connect to MySQL: " . mysqli_connect_error();
  }


$log = new logger(); //this creates the class and logs the current visit
//to output the log
//$log->outputLog();
if ($log->numRecentVisits() > 5){
	if(!in_array($_SERVER['REMOTE_ADDR'],$white_list)){
    die ('Too many visits today. Please try again tomorrow or Contact Support to resolve this issue.'); //this kills the script if there have been too many visits
	}  else {
	//echo "This is your visit no:", $log->numRecentVisits()." today.";
	}
	}

class logger{

    /*
     * sql statement for creating the logging table
     * create table visitorlog
    (    visitID int(10) auto_increment primary key,
        visitIP varchar(15),
        visitURI varchar(255),
        visitReferer varchar(255),
        visitDate DATETIME,
        visitAgent varchar(255)
    )

    public function __construct(){

        $this->agent = $_SERVER['HTTP_USER_AGENT'];
        $this->uri = $_SERVER['REQUEST_URI'];
        $this->ip = $_SERVER['REMOTE_ADDR'];
        $this->ref = empty($_SERVER['HTTP_REFERER']) ? null : $_SERVER['HTTP_REFERER'];

        $this->visitDate = date($strform);

		//echo $sql;
         mysqli_query($con, $sql);
    }
    
    public function numRecentVisits(){
