<?php
   //Creating the connection
   $con = mysqli_connect("localhost", "root", "password", "mydb");

   $query = "CREATE TABLE Test(Name VARCHAR(255), AGE INT)"; 
   mysqli_query($con, $query);

   //initiating the statement
   $stmt =  mysqli_stmt_init($con);

   $res = mysqli_stmt_prepare($stmt, "INSERT INTO Test values(?, ?)");
   mysqli_stmt_bind_param($stmt, "si", $Name, $Age);
   $Name = 'Raju';
   $Age = 25;
   print("Record Inserted.....");

   //Executing the statement
   mysqli_stmt_execute($stmt);

   //Closing the statement
   mysqli_stmt_close($stmt);

   //Closing the connection
