What are some best practices for handling dataset updates in PHP without adding additional columns?

When updating datasets in PHP without adding additional columns, one common approach is to use associative arrays to map the updated values to their corresponding columns in the database. This allows for flexibility in updating specific columns without altering the database schema. By dynamically constructing the SQL query based on the updated values, you can efficiently update the dataset without the need for additional columns. 

// Sample code for updating dataset without adding additional columns
$updatedValues = [
    'column1' => 'new value 1',
    'column2' => 'new value 2',
    'column3' => 'new value 3'
];

// Construct the SQL query dynamically based on the updated values
$query = "UPDATE table_name SET ";
foreach ($updatedValues as $column => $value) {
    $query .= "$column = '$value', ";
}
$query = rtrim($query, ', ') . " WHERE condition";

// Execute the query to update the dataset
// $pdo is assumed to be the PDO object for database connection
$statement = $pdo->prepare($query);
$statement->execute();
