What are the potential issues or limitations when trying to access external website data with PHP?

One potential issue when accessing external website data with PHP is that the target website may have security measures in place to prevent scraping or unauthorized access. To solve this, you can try using cURL to make HTTP requests with headers that mimic a regular browser. 

$url = 'https://www.example.com/data';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.3');
$data = curl_exec($ch);
curl_close($ch);

echo $data;
