How can PHP developers avoid conflicts when switching between different databases on the same server?

When switching between different databases on the same server, PHP developers can avoid conflicts by using different connection objects for each database. By creating separate instances of the database connection for each database, developers can ensure that the queries and transactions do not interfere with each other. This approach helps maintain the integrity and consistency of the data in each database. 

// Connect to the first database
$servername1 = "localhost";
$username1 = "username1";
$password1 = "password1";
$dbname1 = "database1";

$conn1 = new mysqli($servername1, $username1, $password1, $dbname1);

// Connect to the second database
$servername2 = "localhost";
$username2 = "username2";
$password2 = "password2";
$dbname2 = "database2";

$conn2 = new mysqli($servername2, $username2, $password2, $dbname2);

// Use $conn1 for queries on database1 and $conn2 for queries on database2
