In the context of the forum thread, what role does the fetch() method play in retrieving data from MySQL queries, and how can it be optimized for consistent results?

The fetch() method is used in PHP to retrieve data from MySQL queries by fetching the next row from the result set. To optimize it for consistent results, you can set the fetch mode to PDO::FETCH_ASSOC to return an associative array. This ensures that the data is consistently returned in a format that is easy to work with. 

// Set the fetch mode to PDO::FETCH_ASSOC for consistent results
$stmt = $pdo->prepare("SELECT * FROM table");
$stmt->execute();
$result = $stmt->fetch(PDO::FETCH_ASSOC);

// Loop through the results
while ($row = $stmt->fetch(PDO::FETCH_ASSOC)) {
    // Process each row as needed
}
