$username=$POST["username"]; 
$password=$POST["password"]; 


$mysql_qry=" insert into logins(name,surname,age,username,password) values ('$name','$surname','$age','$username','$password')"; 


if($conn->query($mysql_qry)==TRUE){ 

    echo "insert successful"; 


} 
else { 


    echo "Error: ". $mysql_qry . "<br>" . $conn->error; 
} 

$conn->close(); 


?>
