What are the best practices for ensuring that only URLs corresponding to a specific article number are generated in PHP?

To ensure that only URLs corresponding to a specific article number are generated in PHP, you can use regular expressions to validate the input and generate the URL based on the article number. This can help prevent any unauthorized access or manipulation of the URLs. 

<?php
$articleNumber = 123; // Replace with the specific article number

if (preg_match('/^[0-9]+$/', $articleNumber)) {
    $url = "https://example.com/article/{$articleNumber}";
    echo $url;
} else {
    echo "Invalid article number";
}
?>
