Create a form-data object in php back end

I have to send files from my php back end to an API as form-data objects. These files were created directly in the back end and the sending is not associated with any HTML form.

The API documentation provides an example of sending a form-data object but in python, here it is:

files=[
  ('file',('owl-50267_1920.jpg',open('dataset/img/owl-1.jpg','rb')))
]

How can I do the same thing in php ? Thank you

Here is how to create a form-data object in PHP:

$file = ['file' => new CURLFILE('path/to/file.ext')];

Example of usage:

<?php

$curl = curl_init();

curl_setopt_array($curl, [
  CURLOPT_URL => 'API endpoint URL',
  CURLOPT_RETURNTRANSFER => true,
  CURLOPT_MAXREDIRS => 10,
  CURLOPT_TIMEOUT => 0,
  CURLOPT_FOLLOWLOCATION => true,
  CURLOPT_CUSTOMREQUEST => 'POST',
  CURLOPT_POSTFIELDS => ['file' => new CURLFILE('path/to/file.ext')],
  CURLOPT_HTTPHEADER => ['X-API-KEY': 'api key']
]);

$response = curl_exec($curl);

curl_close($curl);
echo $response;
