How can the use of trigger_error be optimized in PHP database classes to align with best practices for error handling and debugging?

When using trigger_error in PHP database classes for error handling, it is important to provide informative error messages and handle exceptions appropriately to aid in debugging. One way to optimize the use of trigger_error is to include relevant information such as the SQL query that caused the error or the specific error code returned by the database. Additionally, it is recommended to log errors to a file or database for later analysis. 

// Example of optimized trigger_error usage in a PHP database class
function query($sql) {
    $result = mysqli_query($this->connection, $sql);
    
    if(!$result) {
        $error_msg = "Error executing query: " . mysqli_error($this->connection);
        $error_msg .= "\nSQL Query: " . $sql;
        
        trigger_error($error_msg, E_USER_ERROR);
        
        // Log error to a file
        error_log($error_msg, 3, "error.log");
        
        return false;
    }
    
    return $result;
}
