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.Basic curl examples

Basic curl examples
Откако ќе го компајлирате PHP со поддршка за cURL, можете да почнете да ги користите функциите на cURL. Основната идеја зад функциите на cURL е дека иницирате cURL сесија користејќи го curl_init(), потоа можете да ги поставите сите ваши опции за пренос преку curl_setopt(), потоа можете да ја извршите сесијата со curl_exec().
Here is a simple example that uses the cURL functions to send a POST request:
Example #1 Using PHP's cURL module to send a POST request
<?php
$data = ['foo' => 'bar', 'baz' => 48];
$url = "http://www.example.com/handler.php";
$ch = curl_init($url);
// tell CURL to return the response instead of sending it to stdout
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// set the POST data, corresponding method and headers
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data));
// send the request and get the response
$response = curl_exec($ch);
if(curl_error($ch)) {
// handle the error, or just
throw new RuntimeException(curl_error($ch));
}Another example that uses the cURL functions to send a raw JSON POST request:
Example #2 Using PHP's cURL module to send a JSON POST request
<?php
$post_data = ['foo' => 'bar', 'baz' => 48];
$url = "http://www.example.com/api/endpoint";
$ch = curl_init($url);
// tell CURL to return the response instead of sending it to stdout
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// set the POST data and corresponding method
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($post_data));
// set the required header
curl_setopt($ch, CURLOPT_HTTPHEADER, ['Content-Type: application/json']);
// send the request and get the response
$response = curl_exec($ch);
if(curl_error($ch)) {
// handle the error, or just
throw new RuntimeException(curl_error($ch));
}Here is another example that uses the cURL functions to fetch the example.com homepage into a file:
Example #3 Using PHP's cURL module to fetch the example.com homepage
<?php
$ch = curl_init("http://www.example.com/");
$fp = fopen("example_homepage.txt", "w");
curl_setopt($ch, CURLOPT_FILE, $fp);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_exec($ch);
if(curl_error($ch)) {
fwrite($fp, curl_error($ch));
}
fclose($fp);
