How can PHP developers ensure proper error handling when attempting file transfers using URLs?

When attempting file transfers using URLs in PHP, developers should ensure proper error handling by checking for errors during the transfer process. This can be done by using functions like `file_get_contents()` or `curl` to fetch the file and checking for any errors or exceptions that may occur. Additionally, developers should consider using try-catch blocks to handle exceptions gracefully and provide meaningful error messages to the user. 

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

try {
    $file_content = file_get_contents($url);
    if ($file_content === false) {
        throw new Exception("Error fetching file from URL");
    }
    
    // Process the file content here
    
} catch (Exception $e) {
    echo "An error occurred: " . $e->getMessage();
}
