What is the potential issue with including files using URLs in PHP?

Including files using URLs in PHP can pose a security risk as it allows for remote file inclusion, which can lead to code execution vulnerabilities. It is recommended to include files using local file paths instead of URLs to mitigate this risk. By using local file paths, you ensure that only files within your server are included, preventing any external code execution. 

// Example of including a file using a local file path
include_once('/path/to/local/file.php');
