In PHP, what steps should be taken to ensure that database operations are successful, especially when creating and interacting with tables multiple times?

When creating and interacting with tables multiple times in PHP, it is important to check for errors during database operations to ensure their success. One way to do this is by using error handling techniques such as try-catch blocks to catch any exceptions that may occur during the execution of SQL queries. 

<?php

// Establish a database connection
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "dbname";

try {
    $conn = new PDO("mysql:host=$servername;dbname=$dbname", $username, $password);
    $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

    // Your SQL queries to create or interact with tables go here

} catch(PDOException $e) {
    echo "Error: " . $e->getMessage();
}

// Close the connection
$conn = null;

?>
