What legal considerations should be taken into account when scraping data from external websites for display on one's own site?

When scraping data from external websites for display on your own site, it is important to consider the legal implications of doing so. Make sure to review the terms of service of the website you are scraping from to ensure that you are not violating any copyrights or terms of use. Additionally, consider implementing measures such as obtaining permission from the website owner or using an API if available to access the data in a legal manner.

// Example of using cURL to scrape data from a website
$url = 'https://www.example.com/data';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$output = curl_exec($ch);
curl_close($ch);

// Display the scraped data on your own site
echo $output;
