$stmt = $pdo->prepare("SELECT * FROM users"); $stmt->execute(); $results = $stmt->getResults();Here, $pdo is a PDO object representing the database connection. The $results variable will contain an array of associative arrays, where each associative array represents a row from the "users" table. This function is often used in conjunction with a foreach loop to iterate over the rows in the result set and perform further processing. This function is commonly used in PHP database libraries such as the PDO or mysqli extensions.
