How Can I Successfully Post Images as Multipart/Form-Data Using cURL in PHP?

Posting Images as Multipart/Form-Data in cURL

Issue:

Users encounter difficulties posting images using cURL in PHP with multipart/form-data headers, despite being able to communicate effectively for other API requests. Current efforts have failed to resolve the image posting challenge.

Proposed Solution:

As of PHP versions 5.6 and 7, using $filePath in CURLOPT_POSTFIELDS without CURLOPT_SAFE_UPLOAD set is deprecated. In PHP 7, $filePath is entirely removed. To address this, implement a CurlFile object.

Implementation:

$fields = [
    'name' => new \CurlFile($filePath, 'image/png', 'filename.png')
];
curl_setopt($resource, CURLOPT_POSTFIELDS, $fields);

This approach allows for posting images as multipart/form-data, adhering to the RFC specification.
