How can the next() function be correctly utilized in PHP to iterate through database records?

When iterating through database records in PHP, the next() function can be used in conjunction with the fetch() method to move the result pointer to the next record in the result set. This allows for sequential processing of each record returned by the database query. 

// Assuming $stmt is a prepared statement object

// Execute the query
$stmt->execute();

// Fetch the first record
$row = $stmt->fetch();

// Iterate through the records using next() and fetch()
while($row) {
    // Process the record
    echo $row['column_name'] . "\n";

    // Move to the next record
    $row = $stmt->fetch();
}
