What are some best practices for handling multiple IDs returned from a SQL query in PHP?

When handling multiple IDs returned from a SQL query in PHP, one best practice is to store the IDs in an array to easily iterate over them. This allows you to perform operations on each ID individually or collectively. Another best practice is to use prepared statements to prevent SQL injection attacks when querying the database for IDs. Lastly, consider using a foreach loop to process each ID returned from the query. 

// Assuming $db is your database connection and $query is your SQL query
$stmt = $db->prepare($query);
$stmt->execute();
$ids = $stmt->fetchAll(PDO::FETCH_COLUMN);

foreach ($ids as $id) {
    // Perform operations on each ID
    echo $id . "<br>";
}
