$curlConfig = array( CURLOPT_URL => "http://www.example.com/yourscript.php", CURLOPT_POST => true, CURLOPT_RETURNTRANSFER => true, CURLOPT_POSTFIELDS => array( 'field1' => 'some date', 'field2' => 'some other data', )

It is important to notice that when using curl to post form data and you use an array for CURLOPT_POSTFIELDS option, the post will be in multipart format
<?php
$params=['name'=>'John', 'surname'=>'Doe', 'age'=>36)
$defaults = array(
CURLOPT_URL => 'http://myremoteservice/',
CURLOPT_POST => true,
CURLOPT_POSTFIELDS => $params,
);
$ch = curl_init();
curl_setopt_array($ch, ($options + $defaults));
?>
This produce the following post header:
--------------------------fd1c4191862e3566
Content-Disposition: form-data; name="name"
Jhon
--------------------------fd1c4191862e3566
Content-Disposition: form-data; name="surnname"
Doe
--------------------------fd1c4191862e3566
Content-Disposition: form-data; name="age"
36
--------------------------fd1c4191862e3566--
Setting CURLOPT_POSTFIELDS as follow produce a standard post header
CURLOPT_POSTFIELDS => http_build_query($params),
Which is:
name=John&surname=Doe&age=36
This caused me 2 days of debug while interacting with a java service which was sensible to this difference, while the equivalent one in php got both format without problem.

<?php
$ch = curl_init();
$url = "https://example.com/api";
$headers = array( 'Content-Type: application/json', 'Authorization: Bearer your_access_token'
);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
if ($response === false) { echo 'Curl error: ' . curl_error($ch);
} else { // Process the response echo $response;
}
curl_close($ch);
?>
