How can the issue of generating the same article number in each row be resolved in PHP?

The issue of generating the same article number in each row can be resolved by using a unique identifier for each row, such as an auto-incrementing primary key in the database. This ensures that each row will have a distinct identifier, even if the article number is the same. 

// Assuming we have a database table named 'articles' with an auto-incrementing primary key column named 'id'

// Connect to the database
$pdo = new PDO('mysql:host=localhost;dbname=your_database', 'username', 'password');

// Select all articles from the database
$stmt = $pdo->query('SELECT * FROM articles');

// Fetch and display each article with its unique identifier
while ($row = $stmt->fetch()) {
    echo 'Article ID: ' . $row['id'] . ' | Article Number: ' . $row['article_number'] . '<br>';
}
