What adjustments can be made to the code snippet provided to ensure that only new entries in a database are flagged with a graphic in PHP?

The issue can be solved by adding a condition to check if the entry already exists in the database before flagging it with a graphic. This can be done by querying the database to see if the entry already exists based on a unique identifier. If the entry does not exist, then the graphic can be added. 

// Check if the entry already exists in the database
$query = "SELECT * FROM your_table WHERE unique_identifier = :unique_identifier";
$stmt = $pdo->prepare($query);
$stmt->bindParam(':unique_identifier', $unique_identifier);
$stmt->execute();

if($stmt->rowCount() == 0){
    // Add the graphic for new entry
    echo "<img src='new_entry.png' alt='New Entry'>";
}
