Code should be

<?php

    #FileName = "Connection_php_mysql.htm"
    #Type = "MYSQL"
    #HTTP = "true"

    $hostname_Main_DB = "localhost";
    $database_Main_DB = "mydb";
    $username_Main_DB = "root";
    $password_Main_DB = "";

    $con = mysqli_connect($hostname_Main_DB,$username_Main_DB,$password_Main_DB, $database_Main_DB) or die ( "Failed to connect to MySQL: " . mysqli_connect_errno());

    $db=mysqli_select_db($database_Main_DB,$con) or die( "Failed to connect to MySQL: ".mysqli_connect_errno());
?>

You should remove “new”. For more information read this

Edit :-

Also you have added . in between two variable that should be ,

$username_Main_DB. $password_Main_DB replace this with $username_Main_DB,$password_Main_DB
