What are some best practices for managing database entries in a MySQL database using PHP?

When managing database entries in a MySQL database using PHP, it is important to use prepared statements to prevent SQL injection attacks and ensure data integrity. Additionally, it is recommended to validate user input before inserting or updating database entries to prevent errors. Lastly, consider implementing error handling to gracefully handle any database-related errors that may occur. 

// Connect to MySQL database
$mysqli = new mysqli("localhost", "username", "password", "database");

// Check connection
if ($mysqli->connect_error) {
    die("Connection failed: " . $mysqli->connect_error);
}

// Prepare a SQL statement using a prepared statement
$stmt = $mysqli->prepare("INSERT INTO table_name (column1, column2) VALUES (?, ?)");
$stmt->bind_param("ss", $value1, $value2);

// Set values for the prepared statement
$value1 = "value1";
$value2 = "value2";

// Execute the prepared statement
$stmt->execute();

// Close the statement and database connection
$stmt->close();
$mysqli->close();
