connect to mysql in php code example
Example 1: php connect to mysql
$servername = "localhost";
$username = "username";
$password = "password";
$conn = new mysqli($servername, $username, $password);
if ($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');

if(!$con){
die ("Connection Terminated! by Die() function". mysqLi_connect_error());
}
else {
echo "Connection Succefully Happened! <br>";
}
?>
