What are the potential issues when using fopen to open a file from a URL in PHP?

When using fopen to open a file from a URL in PHP, potential issues can arise due to security concerns and limitations of the fopen function. To solve this, it is recommended to use cURL, which provides more control and security when working with remote files. 

$url = 'https://www.example.com/file.txt';

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

$file_contents = curl_exec($ch);

curl_close($ch);

// Process the file contents as needed
