<!DOCTYPE html>
<html lang="en">
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <meta http-equiv="X-UA-Compatible" content="ie=edge">
    <title>home page</title>
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "mydb";
// Create connection
$conn = mysqli_connect($servername, $username, $password, $dbname);
// Check connection
if (!$conn) {
    die("Connection failed: " . mysqli_connect_error());
$query = "SELECT id, firstname, lastname FROM students";
$result = mysqli_query($conn, $query);
if (mysqli_num_rows($result) > 0) {
    while($row = mysqli_fetch_assoc($result)) {
        echo " Name: " . $row["firstname"]. " " . $row["lastname"]. "<br>";
} else {
    echo "0 results";
  1. First, we write <! DOCTYPE html> which we used as an instruction to the web browser about what version of HTML file is written in.
  2. Secondly, the <html> tag is used to indicate the beginning of an HTML document.
  3. As above now <head> tag is used to contain information about web page. In this tag a <title> tag is used which helps us to specify a webpage title. Both <head> and <title> tags are Paired tags. So, both have </head> and </title> ending tags respectively.
  4. Here, then we create a body tag. All the content which we want to show on browser’s screen or display is always written inside this codes.
  5. Here, inside body as we can see that we use php tags and inside them we establish our connection with database and when our connection established successfully.
  6. Then our query runs in which we use select query on two columns whereas our table name is students. It means that our student table only two columns are showed having name as firstname and lastname.
  7. Here are many other method with help of which we can use select query. We will learn them one by one in next articles. Then our connection with query checked. If is true then our data got displayed on screen.
  8. At last, the <body> and <html> tags are closed with </body> and </html> respectively.
