How to convert a file into File Entity

Question

I need to use file_copy in a custom module in D8.

The function file_copy requires the first parameter to be a File Entity. Here is what I have tried but it doesn't work and returns an error:

TypeError: Argument 1 passed to file_copy() must be an instance of Drupal\file\FileInterface, instance of stdClass given.

$file_path = drupal_realpath("public://Testttt58.png");
$file = (object) array(
            'uid' => 1,
            'uri' => $file_path,
            'filemime' => mime_content_type($file_path),
            'display' => 1,
            'filename' => "Testttt58.png"
);
$fileUpload = file_copy($file, "public://TestFolder", FILE_EXISTS_RENAME);

Here is the output of kint($file);

How can I solve this?

Answer 1

Just use something like this:

use Drupal\file\Entity\File;
$file = File::create([
  'uri' => $file_path,
  'filemime' => mime_content_type($file_path),
  'filename' => "Testttt58.png",
]);
$fileUpload = file_copy($file, "public://TestFolder", FILE_EXISTS_RENAME);

Answer 2

You can use file_save_data to save a file and create the managed file object.

e.g:

$filepath = 'public://Testttt58.png';
// Save the file, using the file contents in $data
$file = file_save_data($data, $filepath, FILE_EXISTS_REPLACE)
