Warning: mysqli_connect(): MySQL server has gone away

I wrote a simple PHP code to connect to the MySQL server as below

<?php

$username = "root";
$password = "Kepwd";
$hostname = "localhost:81";

//connection to the database
$dbhandle = mysqli_connect($hostname, $username, $password)
  or die("Unable to connect to MySQL");
echo "Connected to MySQL<br>";

but this generates the following errors. I found some topics regarding this issue in google and Stack Overflow. but those don't help me.

you forget to specify the database name after entering database name try again. The syntax should be like this

<?php
$con = mysqli_connect("localhost","my_user","my_password","my_db");
// Check connection
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
?>

The error is here:

$hostname = "localhost:81";

You are not connecting to MySQL, but to Apache server. If you didn't change MySQL port just use 

$hostname = "localhost";
