how to connect html to sql database code example

Example 1: php connect to mysql

$servername = "localhost";
$username = "username";
$password = "password";

// Create connection
$conn = new mysqli($servername, $username, $password);

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


Simplified

$conn = mysqli_connect('localhost', 'username', 'password');
$database = mysqli_select_db($conn, 'database');

Example 2: connect html to mysql database

$con = mysqli_connect("localhost","your_localhost_database_user","your_localhost_database_password","your_localhost_database_db");

Example 3: connect html to mysql database

$con = mysqli_connect('localhost', 'root', '',’db_connect’);
The “db_connect” is our database name that we created before.
After connection database you need to take post variable from the form. See the below code
$txtName = $_POST['txtName'];
$txtEmail = $_POST['txtEmail'];
$txtPhone = $_POST['txtPhone'];
$txtMessage = $_POST['txtMessage'];

Example 4: connect html to mysql database

<?php
//Step1
 $db = mysqli_connect('localhost','username','password','database_name')
 or die('Error connecting to MySQL server.');
?>

<html>
 <head>
 </head>
 <body>
 <h1>PHP connect to MySQL</h1>
</body>
</html>
