What are the risks of scraping content from another website to display on your own site, especially if the other site undergoes structural changes?

Scraping content from another website without permission can lead to legal issues, as it may violate copyright laws. Additionally, if the other website undergoes structural changes, your scraping script may break, leading to outdated or incorrect information being displayed on your site. To avoid these risks, it is best to obtain permission from the website owner to use their content or to utilize APIs provided by the website for accessing their data. 

// Example of using cURL to access a website's content
$ch = curl_init();
$url = "http://www.example.com";
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$output = curl_exec($ch);
curl_close($ch);

// Use regular expressions or a DOM parser to extract specific content from $output
