use php to parse json data posted from another php file - php

Question

my web hosting has blocked the outward traffic so i am using a free web hosting to read data and post it to my server but the problem is that my php file receives data in the $_REQUEST variable but is not able to parse it.
post.php
function postCon($pCon){
//echo $pCon;
$ch = curl_init('http://localhost/rss/recv.php');
curl_setopt ($ch, CURLOPT_POST, 1);
curl_setopt ($ch, CURLOPT_POSTFIELDS, "data=$pCon");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$d=curl_exec ($ch);
echo $d."<br />";
curl_close ($ch);
}
recv.php
<?php
if(!json_decode($_REQUEST['data']))
echo "json error";
echo "<pre>";
print_r($data);
echo "</pre>";
?>
every time it gives json error.
but echo $_REQUEST['data'] gives the correct json data.
plz help.

Answer 1

Should not this ?
$posts = array('data'=>$pCon);
curl_setopt ($ch, CURLOPT_POSTFIELDS, $posts);
even the example in doc show that
from doc
The full data to post in a HTTP "POST" operation. To post a file, prepend a filename with # and use the full path. This can either be passed as a urlencoded string like 'para1=val1&para2=val2&...' or as an array with the field name as key and field data as value. If value is an array, the Content-Type header will be set to multipart/form-data. As of PHP 5.2.0, files thats passed to this option with the # prefix must be in array form to work.
your existing way should work too,
is it possible that $pCon contains some urlencoded values such as =, ? ?

Answer 2

$posts = array('data'=>$pCon);
curl_setopt ($ch, CURLOPT_POSTFIELDS, $posts);
this worked.
(the person who answered this question deleted the post so i couldnt catch his name, so thankx)
edit:
there still was a small error every quote (") was changed to (\") i had a very hard time correcting this so now i am not sending data in json directly but first base64 encode it and when the page receives it , it base64 decodes it.
now this workds flawlessly...
thankyou all...
