👉Open xampp or wampp and start its server.

👉Create a database(in my case it is anjudb) and then table(in my case it is user) .

👉create a folder (in my case it is phpfolder) then create a file(in my case index.php) then copy paste te bellow code)  and go to the url  http://localhost/yourfoldername/.

👉This will help in clearing basic php logic . 

<!-- //connection to database -->

<?php

   error_reporting(0); 

   $host="localhost";

   $user="root";

   $password="";

   $database="anjudb";

   $con=mysqli_connect($host,$user,$password,$database);

   if($con) {echo '<h1>Connected to MySQL</h1>';} 

   else {echo '<h1>MySQL Server is not connected</h1>';}

?>

<!-- //connection to database end -->

<!-- //form data insertion  start -->

<?php 

   if($_POST["sub"])

   {

    $name=$_POST['firstname'];

    $sql_query="INSERT INTO `user`(`name`) VALUES ('$name')";

    $response= mysqli_query($con,$sql_query);

    if( $response ){echo "Record Added Sucessfully";}

    else{echo "Error";}

    $con->close();

   }

?>

<!-- //form data insertion  end -->
