Từ php, bạn chỉ cần tạo kết nối mới với 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();
?>
