[SOLVED] Updating WooCommerce product via REST API using PHP CURL

Issue

It seems as if $data isn't correct. I can list products and I get the whole product JSON as a response. But the product in WooCommerce doesn't change the price. When I do the same thing via curl command line, the update is working.
Referring to that: https://woocommerce.github.io/woocommerce-rest-api-docs/?php#update-a-product

What am I doing wrong?

<?php

$url = "https://wooexample.com/wp-json/wc/v3/products/455";

$curl = curl_init($url);
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_PUT, true);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);

$headers = array(
   "Content-Type: application/json",
   "Authorization: Basic " . base64_encode ( 'ck_33fbff7b90dcddba9bd4cbedaeda6b2fa3:cs_4156da18fc357b288e42a7e7b75fa6682b' ),
);
// print_r($headers);
curl_setopt($curl, CURLOPT_HTTPHEADER, $headers);

$data = [
    'regular_price' => '24',
    'price' => '24'
];

curl_setopt($curl, CURLOPT_POSTFIELDS, $data);

//for debug only!
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);

$resp = curl_exec($curl);
curl_close($curl);
print_r(json_decode($resp));

Solution

Ty this one, I have checked, it's working perfectly for me.

<?php

$url = "https://localhost/wordpress/wp-json/wc/v3/products/455";

$consumer_key = 'your consumer key put here..';
$consumer_secret = 'your consumer secre put here..';

$headers = array(
    'Authorization' => 'Basic ' . base64_encode($consumer_key.':'.$consumer_secret )
);
$data = array(
    'regular_price' => '24',
    'price' => '24'
);

$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_TIMEOUT, 30);

curl_setopt($curl, CURLOPT_HTTPHEADER, $headers);
curl_setopt($curl, CURLOPT_POSTFIELDS, http_build_query($data));
//for debug only!
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($curl, CURLOPT_USERPWD, "$consumer_key:$consumer_secret");
$resp = curl_exec($curl);
$status_code = curl_getinfo($curl, CURLINFO_HTTP_CODE); 
curl_close($curl);
print_r(json_decode($resp));
