RAW POST using cURL in PHP

I just found the solution, kind of answering to my own question in case anyone else stumbles upon it.

$ch = curl_init();curl_setopt($ch, CURLOPT_URL,            "http://url/url/url" );curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1 );curl_setopt($ch, CURLOPT_POST,           1 );curl_setopt($ch, CURLOPT_POSTFIELDS,     "body goes here" ); curl_setopt($ch, CURLOPT_HTTPHEADER,     array('Content-Type: text/plain')); $result=curl_exec ($ch);

Implementation with Guzzle library:

use GuzzleHttp\Client;use GuzzleHttp\RequestOptions;$httpClient = new Client();$response = $httpClient->post(    'https://postman-echo.com/post',    [        RequestOptions::BODY => 'POST raw request content',        RequestOptions::HEADERS => [            'Content-Type' => 'application/x-www-form-urlencoded',        ],    ]);echo(    $response->getBody()->getContents());

PHP CURL extension:

$curlHandler = curl_init();curl_setopt_array($curlHandler, [    CURLOPT_URL => 'https://postman-echo.com/post',    CURLOPT_RETURNTRANSFER => true,    /**     * Specify POST method     */    CURLOPT_POST => true,    /**     * Specify request content     */    CURLOPT_POSTFIELDS => 'POST raw request content',]);$response = curl_exec($curlHandler);curl_close($curlHandler);echo($response);
