What are the potential pitfalls of storing multiple URLs in separate columns in a database for PHP applications?

Storing multiple URLs in separate columns in a database for PHP applications can lead to a lack of scalability and maintenance issues. Instead, it is recommended to store multiple URLs in a single column using a JSON or serialized format to keep the data organized and easily retrievable. 

// Storing multiple URLs in a single column using JSON format
$urls = ['https://example.com/page1', 'https://example.com/page2', 'https://example.com/page3'];
$json_urls = json_encode($urls);

// Save $json_urls to the database
