How can special characters in file names be handled when saving images fetched from external websites in PHP?

Special characters in file names can be handled by using PHP's `urlencode()` function to encode the file name before saving it. This function will replace special characters with their URL-encoded equivalents, ensuring that the file name is valid and can be saved without any issues. 

// Get the file name from the URL
$url = "https://example.com/image.jpg";
$fileName = basename($url);

// Encode the file name
$encodedFileName = urlencode($fileName);

// Save the image with the encoded file name
file_put_contents($encodedFileName, file_get_contents($url));
