How can the use of reserved words as column names in SQL queries affect the functionality of PDO in PHP?

Using reserved words as column names in SQL queries can cause conflicts and errors when using PDO in PHP. To avoid this issue, you can enclose the reserved words in backticks (`) in your SQL queries to ensure they are treated as column names by the database engine. 

<?php
$pdo = new PDO("mysql:host=localhost;dbname=mydatabase", "username", "password");

$statement = $pdo->prepare("SELECT `column`, `another_column` FROM my_table");
$statement->execute();

$results = $statement->fetchAll(PDO::FETCH_ASSOC);

foreach ($results as $row) {
    echo $row['column'] . ' - ' . $row['another_column'] . '<br>';
}
?>
