Are there any best practices for renaming and archiving files fetched from external domains in PHP?

When fetching files from external domains in PHP, it is a good practice to rename the files to avoid conflicts and improve organization. Additionally, archiving the fetched files can help with storage management and backup purposes. One way to achieve this is by using unique identifiers or timestamps as part of the new file names and storing the files in a designated directory.

// Fetching a file from an external domain
$fileUrl = 'https://www.example.com/image.jpg';
$fileName = basename($fileUrl);

// Generate a unique identifier or timestamp for renaming
$newFileName = uniqid() . '_' . $fileName;

// Directory for storing archived files
$archiveDir = 'archives/';

// Save the fetched file with the new name in the archive directory
file_put_contents($archiveDir . $newFileName, file_get_contents($fileUrl));
