In what scenarios would it be beneficial to store database update statements in a text file before importing them into a database using PHP?

Storing database update statements in a text file before importing them into a database using PHP can be beneficial when you need to keep a record of the changes made to the database for auditing purposes or for easy rollback in case of errors during the import process. It can also be useful when dealing with large amounts of update statements that need to be executed in a specific order. 

// Read update statements from a text file and execute them in a database

// Open the text file containing update statements
$file = fopen('update_queries.txt', 'r');

// Connect to the database
$connection = new mysqli('localhost', 'username', 'password', 'database');

// Loop through each line in the text file and execute the update statements
while ($query = fgets($file)) {
    $result = $connection->query($query);
    
    if (!$result) {
        echo "Error executing query: " . $connection->error;
    }
}

// Close the file and database connection
fclose($file);
$connection->close();
