Variable inside an array does not work

Question

is a CLOUDINARY image upload system.

When I use a fixed value for PUBLIC_ID, it works!

$files["remote"] = \Cloudinary\Uploader::upload($sample_paths["couple"],
array_merge($default_upload_options, array(
  "public_id" => '8273',
))

However, when I use a variable for PUBLIC_ID, the result of PUBLIC_ID simply from NULL

$files["remote"] = \Cloudinary\Uploader::upload($sample_paths["couple"],
array_merge($default_upload_options, array(
  "public_id" => "$idbusca",
))

What can be?

Friend first on

$files["remote"] = \Cloudinary\Uploader::upload($sample_paths["couple"],
array_merge($default_upload_options, array(
  "public_id" => "$idbusca",
))

Remove the double quotes (") around the variable $idbusca.

After this check that this variable is not really empty/null can be this way

echo 'Var $idbusca:<br/><pre>';
var_dump($idbusca);
echo '</pre>';

$files["remote"] = \Cloudinary\Uploader::upload($sample_paths["couple"],
array_merge($default_upload_options, array(
  "public_id" => $idbusca,
))

Because the way it is there it should return the value correctly. If it is really empty the ideal is to go through the code by checking where it has the information and where it "lost".
