What is the significance of URL file-access being allowed in PHP for downloading files from external sources?
Allowing URL file-access in PHP allows downloading files from external sources by enabling the use of URLs as file paths in functions like `file_get_contents()` and `fopen()`. This can be useful for fetching remote files or resources for processing or storage on the local server. However, enabling URL file-access can pose security risks if not used carefully, as it opens up the possibility of accessing sensitive files or resources on remote servers.
// Enable URL file-access for downloading files from external sources
ini_set('allow_url_fopen', 1);
// Example usage: Download a file from a remote server
$file_content = file_get_contents('https://www.example.com/file.txt');
// Process or store the downloaded file content as needed
