What are some considerations to keep in mind when inheriting a PHP project with existing database structures?

When inheriting a PHP project with existing database structures, it's important to familiarize yourself with the database schema and understand how the data is organized. You should also review the existing PHP code to see how it interacts with the database tables and make note of any specific queries or data manipulation functions being used. Additionally, consider documenting the database structure and any custom functions or classes related to database operations to help with future maintenance and troubleshooting. 

// Example PHP code snippet to connect to an existing database in a PHP project
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database_name";

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

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