PHP SQL :Cara menyimpan data ke beberapa database dari satu bentuk html ATAU cara menyalin data dari satu database ke database lain secara otomatis

Dari php Anda hanya perlu membuat koneksi baru ke DB.

<?php
   $servername = "localhost";
   $username = "database1";
   $password = "xxxxxxxx";
   $dbname = "database1";


   $servernameS = "localhost";
   $usernameS = "database2";
   $passwordS = "xxxxxxxx";
   $dbnameS = "database2";

   // Create connection
   $conn = new mysqli($servername, $username, $password, $dbname);
   $connS = new mysqli($servernameS, $usernameS, $passwordS, $dbnameS);

   // Check connection
  if ($conn->connect_error) {
       die("Connection failed: " . $conn->connect_error);
   }
   if ($connS->connect_error) {
       die("Connection failed: " . $connS->connect_error);
   }

   //escape variables for security
   $fname = mysqli_real_escape_string($conn, $_POST['fname']);
   $lname = mysqli_real_escape_string($conn, $_POST['lname']);

   $sql = "INSERT INTO mytable (fname,lname) 
   VALUES ('$fname','$lname')";

    if ($conn->query($sql) === TRUE) {
     echo "Successfully Saved";

    } else {
      echo "Error: Go back and Try Again ! " . $sql . "<br>" . $conn->error;
    }

    if ($connS->query($sql) === TRUE) {
     echo "Successfully Saved";

    } else {
      echo "Error: Go back and Try Again ! " . $sql . "<br>" . $connS->error;
    }
    $conn->close();
    $connS->close();

   ?>
