Description:
------------
When setting a number of curl options through curl_setopt_array and using post, the postfields options are not being set properly and are reported as errored in the response. When the curl_setopt options are set seperately then the response is valid.

This is for postfields only. Setting the curl options through curl_setopt_array and seperately for GET work ok

Works - using yahoo webservice example. Freely available at http://developer.yahoo.com/search/siteexplorer/V1/inlinkData.html
------
<?php
error_reporting(E_ALL);
// The POST URL and parameters
$request= 'http://search.yahooapis.com/SiteExplorerService/V1/inlinkData';
$appid = 'YahooDemo';
$query = 'http://search.yahoo.com';
$postargs = 'appid='.$appid.'&query='.urlencode($query).'&results=2';
$ch = curl_init($request);
curl_setopt ($ch, CURLOPT_POST, true);
curl_setopt ($ch, CURLOPT_POSTFIELDS, $postargs);
curl_setopt ($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt ($ch, CURLOPT_HEADER, true);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
curl_close($ch);
// Output the XML
echo htmlspecialchars($xml, ENT_QUOTES);

ERRORS in xml
-------------
<?php
error_reporting(E_ALL);
// The POST URL and parameters
$request=  'http://search.yahooapis.com/SiteExplorerService/V1/inlinkData';
$appid = 'YahooDemo';
$query = 'http://search.yahoo.com';
$postargs = 'appid='.$appid.'&query='.urlencode($query).'&results=2';
$ch = curl_init($request);
$options = array(CURLOPT_POST => true,
		 CURLOPT_POSTFIELDS, $postargs,
		 CURLOPT_FOLLOWLOCATION => true,
		 CURLOPT_HEADER => false,
		 CURLOPT_RETURNTRANSFER => true);
curl_setopt_array ($ch, $options);
$response = curl_exec($ch);
curl_close($ch);
echo htmlspecialchars($xml, ENT_QUOTES);

Your code is wrong:

$options = array(CURLOPT_POST => true,
		 CURLOPT_POSTFIELDS, $postargs,
		 CURLOPT_FOLLOWLOCATION => true,
		 CURLOPT_HEADER => false,
		 CURLOPT_RETURNTRANSFER => true);

should be

$options = array(CURLOPT_POST => true,
		 CURLOPT_POSTFIELDS => $postargs,
		 CURLOPT_FOLLOWLOCATION => true,
		 CURLOPT_HEADER => false,
		 CURLOPT_RETURNTRANSFER => true);
