How can the HTTP wrapper error be resolved when using the copy() function for file uploads?

The HTTP wrapper error can be resolved by using the `file_get_contents()` function instead of directly passing the file path to the `copy()` function when uploading files. This error occurs because the `copy()` function does not support URLs and requires a local file path. By using `file_get_contents()` to read the file contents and then writing them to a new file, the HTTP wrapper error can be avoided.

$file_url = 'http://example.com/file.jpg';
$new_file_path = 'uploads/new_file.jpg';

// Get file contents using file_get_contents
$file_contents = file_get_contents($file_url);

// Write file contents to a new file
file_put_contents($new_file_path, $file_contents);
