How to read CURL POST on remote server? - php

Question

This is my cURL POST function:
public function curlPost($url, $data)
{
$fields = '';
foreach($data as $key => $value) {
$fields .= $key . '=' . $value . '&';
}
rtrim($fields, '&');
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, count($data));
curl_setopt($ch, CURLOPT_POSTFIELDS, $fields);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
$result = curl_exec($ch);
$info = curl_getinfo($ch);
curl_close($ch);
}
$this->curlPost('remoteServer', array(data));
How do I read the POST on the remote server?
The remote server is using PHP... but what var in $_POST[] should I read
for e.g:- $_POST['fields'] or $_POST['result']

Answer 1

You code works but i'll advice you to add 2 other things
A. CURLOPT_FOLLOWLOCATION because of HTTP 302
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);
B. return in case you need to output the result
return $result ;
Example
function curlPost($url, $data) {
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);
$result = curl_exec($ch);
$info = curl_getinfo($ch);
curl_close($ch);
return $result;
}
print(curlPost("http://yahoo.com", array()));
Another Example
print(curlPost("http://your_SITE", array("greeting"=>"Hello World")));
To read your post you can use
print($_REQUEST['greeting']);
or
print($_POST['greeting']);

Answer 2

as a normal POST request ... all data posted can be found in $_POST ... except files of course :) add an &action=request1 for example to URL
if ($_GET['action'] == 'request1') {
print_r ($_POST);
}
EDIT: To see the POST vars use the folowing in your POST handler file
if ($_GET['action'] == 'request1') {
ob_start();
print_r($_POST);
$contents = ob_get_contents();
ob_end_clean();
error_log($contents, 3, 'log.txt' );
}
