Before diving into the extended features of PDO v2.0, let’s take a brief look at what PDO is. PDO, or PHP Data Objects, is a database abstraction layer that provides a uniform interface for accessing different databases in PHP. It allows developers to write database-agnostic code, making it easier to switch between different databases without modifying the code.

For example:

$stmt = $pdo->prepare('SELECT * FROM users'); $stmt->execute(); $stmt->setFetchMode(PDO::FETCH_ASSOC); while ($row = $stmt->fetch()) { // process row $stmt->scrollDown(); } In this example, we use the scrollDown() method to navigate through the result set. PDO v2.0 supports asynchronous queries, which allow developers to execute queries in the background while performing other tasks.
