Managing Database Connections: The below code snippet describes managing database connection methods and features.

<?php

$servemame = “localhost”;

$username = “username”;

$password = “password”;

$DBname = “SchoolDB”;

// Create connection

Sconn = mysqli_connect($servemame, Susername, Spassword,SDBname);

// Check connection

if (! Sconn) {

die(“Ccnnection failed: “ . mysqli_connect_error( ));

}.

echo “Connected successfully”;

?>

In the above code snippet, three variables are used to connect to the Database server. 

They are 

1. $servemame → Database Server IP address

2. $usemame → Database Server User Name

3. $password → Database Server Password 

4. $DB_Name → Database Name 

The mysqli_connect function uses these variables and connect Database server from PHP scripting. If connection gets fail, output will be printed with MySQL error code. Otherwise connection is success.
