What are the recommended steps for handling and interpreting MySQL error messages in PHP?

When handling MySQL error messages in PHP, it is recommended to use the mysqli_error() function to retrieve the error message from the database. This can help in identifying the specific issue that caused the error and take appropriate actions to resolve it. Additionally, using error handling techniques such as try-catch blocks can help in gracefully handling errors and providing meaningful feedback to the user. 

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

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

// Perform SQL query
$result = $mysqli->query("SELECT * FROM table");

// Check for query errors
if (!$result) {
    die("Query failed: " . $mysqli->error);
}

// Process query results
while ($row = $result->fetch_assoc()) {
    // Do something with the data
}

// Close connection
$mysqli->close();
